Casino gift shops are FULL of crap like this. Walk into any one of them and you will find their logo on EVERYTHING! They often give away things like this to new Player's Club members (or frequent players) too.

I would also recomend eBay for this. Just do a search for Blackjack and you will find shirts, sweaters, watches, paperweights, jackets, blah blah blah. I got myself a great blackjack belt buckle and some "Table Limit" signs from the Flamingo blackjack tables there. These items probably won't have any casino logos on them though.
