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.

Greece: Barrel organ

Greece issued this stamp (Scott 1165) featuring a barrel organ in 1975. It was part of a set of twelve stamps featuring musical instruments. Other instruments included in the set:

Lyre (Pontos), (a mural of Byzantine musicians), another lyre (Crete), Tambourine, guitar, bagpipes, lute, pipes and zournadas (a type of reed instrument shown below), (another mural showing singers), drums, kanonaki (a type of harp shown below).

The current stamp is essentially green, with the instrument centered. The shown instrument is nicely decorated with draperies and a picture. There is no descriptive information on the stamp.
