I have a 24b "Mutawakelite Kingdom of Yemen" airmail stamp that I can find no information about. It is not in the Scott catalog (2002 edition) nor can I find any info about it on the Internet. The stamp is approximately 37mm by 50mm, is perforated, and shows a nude sitting on a bed with her backside showing. There is a caption on the left side that says "Dominique Ingres 1780-1867." The face value says "Airmail 24 bogshans" on the middle left of the stamp and the same written in Arabic on the middle right side of the stamp. Internet sites all use the word "Mutawakklite," in discussing the kingdom, but the stamp clearly spells the word "Mutawakelite."
If anyone can point me in the right direction with any information concerning this stamp, I would greatly appreciate it.
