The stamp shown here is from an eBay auction where it was described as a '
Greek prostitution revenue'. I missed the auction, but the seller kindly provided me with the image shown below.
Unfortunately, he couldn't provide any details regarding the stamp's use. The stamp was from a collection he'd purchased, and the description came from a note on the page where the stamp had been mounted.
I'd greatly appreciate hearing from anyone who has knowledge of this stamp, or of Greek prostitution stamps in general
if they really do exist. I know nothing more than the auction description.

I'm hoping there are some Greek revenue collectors on the board. I don't have a catalog of Greek fiscals, and this is, in fact, the only Greek stamp in my collection.
Tanks,
