The legend in a central circle surrounded by grenetis and flowers. All around, musical instruments with, on either side, more or less mirrored and from top to bottom: string, wind and percussion instruments. At noon, the Belgian coat of arms; at 6 o`clock, a musical score. Occasional handwriting in the center of the circle (enlargement in comments)
