There are some matchbooks under the roulette wheel next to the last stack of chips to the right. I can't tell if they say something or they have a building on them. The dealers apron has the beginning of a logo or name on it. There is also a stack of chips by the roulette wheel with inserts. I don't see any wedding rings on the ladies... It might of been used in an advertisement to get some gents to Las Vegas. Tome it looks like there are 2 letters on the chips... DI is a possibility.
