I thought all casinos (at least those in Nevada) and distanced themselves from the tobacco controversy and were supplying only generic ashtrays to their customers. I was surprised to see white ceramic ashtrays at Bellagio last week with the "B" logo on them. They are deeper than the traditional ashtray. I saw them in the high-limit slot area, but they are probably out in other areas as well.
Didn't pick up any as I've given up on the bulky, heavy glass collecting. Anyone interested could probably harvest several the next time in town.
