The blue 'Ostrich Swallowing a Slot Machine' is the only one in the 'I Hit the JP' series that doesn't say Harrah's Club, Mark. I've always thought there should be others but never came across one. There are 17 different cartoon pics in the series, and several varieties of some of them. The scarcest, I believe, is the cowpoke tipping his Stetson to the cowgirl which I've seen only in yellow.
