Belgium issued this stamp (Scott 1199) as part of a set of two in 1985, for its Europa commemoration. 1985 was a "music year" in the Europa program. This stamp includes a profile of Cesar Franck seated at an organ console, with organ pipes in the background. There is a music exerpt included, but I cannot tell what the score is; it's probably not an organ score. The year 1887 is included in the stamp image. It's hard to tell if that's the year of the image of Franck, or if the stamp is issued a couple of years ahead of a centennial! Franck was an incredible composer. Though his organ compositions number exactly twelve, he is closely associated with that instrument, as he was for a years a church organist. Though he was born in Belgium, he is most closely associated with St. Sulpice in Paris.
