Venezuela, Christmas angels

Venezuela issued this stamp in 1967 as part of a set for Christmas. It features a reproduction of Stephan Lochner's La Virgen del Rosal (Virgin in a rose arbor). The original painting hangs in the Wallraf-Richartz-Museum in Cologne, Germany. Painted in 1450, it is a small work, suited for personal or home devotional use. Angels surround the central figure, and each holding musical instruments. Almost obscured by the denomination, the angel at LL is holding a portativ. This angel and its instrument are quite clear in the image of the original painting. This stamp (Scot C976) was for airmail postage.

Netherlands: Drei Pruiken Draaiorgel

Netherlands issued a set of two stamps in 2014, the European Year for musical instruments. The stamps celebrate the Drei Pruiken Draaiorgal, a famous street organ in that country. The instrument is characterized by three be-wigged statues as part of the decoration.

Information about the organ from Hans Timmermann's site:
De firma werd in 1875 opgericht door Orgelbouwer Leon Warnis uit België Oorspronkelijk verhuurde de firma alleen maar draaiorgels, later kwamen daar ook reparaties en nieuwbouw bij. In 1932 nam de familie Perlee de onderneming over en begon een orgelmakers werkplaats in de Westerstraat 119 in Amsterdam, waar deze zich nu nog bevindt.

Het draaiorgel de "Drie Pruiken" werd in 1953 uit de resten van een oud Gavioli-Orgel gebouwd.
Het was de eerste nieuwbouw van de firma na de 2e wereldoorlog. De naam is ontleend aan de drie figuren op de voorzijde die historische kostuums en grote pruiken dragen. De drie pruiken is nog volledig intact. Er wordt zelfs geregeld nieuwe muziek speciaal voor dit bekende orgel gecomponeerd. De drie pruiken is eigendom van Museum Speelklok in Utrecht. Dit museum beheert de grootste collectie straatorgels uit de twintigste eeuw.

The company was founded in 1875 by Orgelbouwer Leon Warnis from Belgium Originally, the company rented only spin organizers, later arrived there including repairs and new construction. In 1932, the Perlee family took over the company and began one- organ workmaker's workshop in the Westerstraat 119 in Amsterdam, where it is still located.

The rotary organ "Drie Wruiken" was built in 1953 from the remains of an old Gavioli organ.
It was the company's first new building after the 2nd World War. The name is derived from the three figures on the front which carry historical costumes and big wigs. The three wigs are still completely intact. Even new music is specially composed for this well-known organ. The three wigs are owned by Museum Speelklok in Utrecht. This museum manages the largest collection of street organizers of the twentieth century.

Lithuania, Coat of Arms

Lithuania has issued several stamps which feature the coats of arms of various regional areas. In 1999 the post issued a set of three. The high-value in this set of three was the coat of arms for Rokiskis. This town of some 16,000 is in the northeast of the country. The arms on Scott 644 is comprised of 4 sections, three of which represent ruling families in the history of the area. The LL quadrant features an organ, specifically that in the St Matthias Church in Rokiskis. The instrument in the church doesn't look much like the representation on the stamp.

This site for Lithuanian organs does not have a listing for Rokiskis (yet).

I was able to find this information about the Matthias Church, including the organ:

The church was finished in 1877, but the interiors. Soon count Tyzenhauzas died. His sister Marija/Marry continued financing and supervising the works. She decided to slightly rebuild the church from the outside too - to make it even more grandeur. She met an Austrian architect Werner Georg from Tyrol, then an architect of Vienna, who prepared a project. The main altar was made in Paris in the workshop of French P. Puossielgue – Rusand. Wooden canopy was made in Belgium, the workshop of Goyers. Much of other altars were too made by Goyers and P. Puossielgue – Rusand workshops. The organ was made by Germans Walcker, workshop in Ludwigsburg, Württemberg. Czech from Austria - Rudolf Liehmann (a son of Antonín Liehmann - the teacher of Antonín Dvořák) was invited to play the organ. With him, more Czechs came to Rokiškis and the musical school was was opened in the town, an orchestra started, that played concerts every weekend. By the way, R. Liehmann married in Rokiškis and stayed to the end of his life there. He is buried in Rokiškis cemetery. 

Aitutaki: Christmas, angels

The island nation of Aitutaki (part of the Cook Island archipelago in the South Pacific) issued a set of 8 stamps in 1994 for Christmas featuring various religious paintings. Two sets of four stamps were denominated 85c and 90c. They featured various representations of the birth of Jesus: Mary, magi, angels, etc. These stamps saw little postal use and are generally collected as attached blocks of four stamps. On the 85c block, the UR stamp (Scott 508b) shows angels on the perimeter, holding musical instruments. One of the angels is holding a portativ organ. Memling painted several versions of the nativity story on various commissions. This particular painting is known as the Donne Triptych and is at the National Gallery, London, UK. It was completed in 1478.

Cambodia (Kampuchea): St Cecilia

Cambodia issued a set of 7 stamps plus a mini-sheet of one additional stamp in 1985, celebrating the international music year. The stamps are basic representations of art works that feature music and musical instruments. The 2 riel stamp (Scott 607) is "St Cecilia" by Bartolomeo Schedoni (1578-1615). On the left edge of the stamp, behind the saint's right shoulder is a small, anonymous positif organ. The saint's left hand is passing in front of her body and reaching for the keys of the instrument. An winged angel is at her left shoulder. In front of Cecilia are a lute and tambourine. Beneath her foot seems to be another stringed instrument. Schedoni painted this oil on canvas work in 1610. The work now hangs in the Galleria Nazionale di Capidimonte in Naples, Italy.

Evora, Portugal: Cathedral

The first building associated with the cathedral's locale was built 1184-1204. It was revised and expanded 1280-1340. It is the largest of Portugal's medieval cathedrals.

The stamp, horizontally oriented, was issued as part of the 2014 set of 10 cathedral stamps. Like others in the series, it has an exterior image in additional to the interior, and features a cross pattern in the perforations. It is denominated .42 euros. The stamp captures the bottom portion of the gallery in which the organ is located. One must look elsewhere for images of the whole instrument.

The Organs of Portugal site is ambivalent about the builder, but suggests installation took place between 1694 and 1710. It was restored by Flentrop in 1967 is is currently playable. For such a large space, the stoplist looks remarkably small.

Beja, Portugal: Cathedral

The cathedral at Beja was begun in 1590 and is dedicated to St James. It was designated a cathedral relatively recently, in 1925. At that time it was renovated and enlarged, and ultimately rededicated in 1937. As such the organ is likewise relatively new.

The stamp for this cathedral was issued in the 2013 series. It features a long view of the nave, with part of the organ just barely visible. One can home in on the organ using the characteristic red  pipe shades as a guide. It was built in 1996 by Egbert Pfaff of Germany. One may view the stop list here. The view of the nave below seems to have been shot just a bit closer to the east end of the church, and thus shows a little bit more of the instrument.
