The only pics I have seen is on pg 142 of the Campiglia and Wells 4th edition (pg 140 in the 3rd edition). I read a interesting story about the history of the chips somewhere regarding the closing of the roulette tables and the owner wrapping the the wheel and a handful of chips in a canvas dropcloth only to be discovered years later in the basement. I will look for the reference ( I can never remember where I read stuff, its annoying)
