The first organ stamp was issued by Liechtenstein in 1938. It featured a portrait Joseph Gabriel Rheinberger and a row of pipes. Rheinberger of course was a native of Liechtenstein born in 1839. The Rheinberger stamp was issued in a mini-sheet of four in 1938 for a philatelic exhibition; the same image was used in 1939 for a stamp issued in a pane of 20 format. This stamp is the first to include images of any part of an organ in the image.
