Found on ebay. The description (courtesy of seller Fred H.):
"This is no ordinary ashtray. It was probably made as a gambling item. It is approx 3 1/2" high and 4 1/2" from opening to opening. One side depicts a 2 of Clubs and the other a Queen of Clubs and 2 poker chips. The holder at the top has some very fine beading. There are no chips nor cracks on the piece. A very interesting item."
