Athens, Greece: Christos Lambrakis Concert Hall

From the wiki page for the Athens concert hall complex I was able to determine that the organ in the Christos Lambrakis Hall was built by Klais, in Germany. From their site I was able to determine the manufacture date, 1993. The site also includes a specification. The concert hall complex was built in 1991 but has added two additional performance spaces since then. The organ in the main hall is the largest in Greece. This stamp (Scott 1774) was issued in 1993 as part of a set of 4 featuring major buildings in Athens. It is the low-value of the set. Other stamps show a museum, a library and a hospital.

Argentina: Kirchner Cultural Center

Argentina issued this stamp in 2015, celebrating the Kirchner Cultural Center in BA. The mini-sheet is actually comprised of a single stamp with 4 colorful labels included. The Kirchner Center began as a Postal center when it was constructed (1911-1928). It was converted to a residence (1946) for the nation's president, but was recently re-invented as an arts facility (2005-2015). Included in the building is a large concert hall, The Blue Whale, which includes a pipe organ. The $20 stamp shows the interior of the concert hall including the organ. The labels show various other aspects of the facility. One of them shows some details of the organ: pipes, drawknobs and keyboards. The four-manual and pedals (56 ranks) instrument was built by Klais in Germany.

Philippines: The Bamboo Organ

Anyone remotely interested in collecting stamps with the pipe organ theme will be familiar with the famous bamboo organ in Las Pinas, Philippines. Chris van Doodewaard has posted a very helpful article on the organ. The builder was a priest, Father Diego Cera. It was begun in 1816, heard in worship in 1821 and called "complete' in 1824 with the addition of a horizontal trumpet stop. The instrument is made almost entirely using bamboo. The horizontal reed pipes are in fact metal. The organ endured its harsh environment for many years but was finally declared unplayable in 1972, shipped to the Klais firm in Germany in 1973, rebuilt in a climate-controlled facility that replicated its "home" conditions. It was returned and re-installed in 1975. The organ has a single keyboard, divided. It was designed and built in a Spanish style.

The organ is featured on a set of three stamps (Scott 903-905) issued in 1964. The second of the three stamps was surcharged and re-issued (Scott 1055) in 1971. Philatelic materials related to these stamps are abundant. I have accumulated envelops and postcards, first day covers and programs all using these stamps in various combinations.
