Gabon first issued this stamp in 1960. Scott catalogues it as the first airmail stamp Gabon issued (C1). Schweitzer is shown with a village vignette, some trees, a book of music by Bach and some organ pipes. Gabon later (in 1963) re-issued this stamp (Scott C11), with a chang ein denomination and an overprint commemorating the 50th anniversary of Schweitzer's arrival in Gabon. The medical-missionary-organist appears on several other Gabonaise stamps, including C159, C269 and C289. This appears to be the only one however that includes organ pipes.
