Guinea-Bissau issued this souvenir sheet August 5, 1985 as the last in a set of stamp honoring musicians and instruments. Guinea-Bissau is on the western coast of Africa and is the region once known as Portuguese Guinea, until the nation declared independence in 1974. It includes the Bissagos Islands.
This souvenir sheet and its stamp feature a portrait of JS Bach and images from the Thomas Kirche in Liepzig Germany where Bach was cantor or music director. The Sauer organ was built in 1889, thus Bach himself never played it. It was restored in 2005. There is a second more Bach-like instrument in the Thomas Kirche now, but again Bach never played it; it was built by the Woehl firm in 2000.
