I finally got my scanner up and running! Here are the scans of some old dice I promised. I don't have any definitive information on any of these dice, but there are some clues.
Pair 1: It'll Do Club
Pair 2: hard to see, but there is a little "HUB" on each six spot--there were a few "Hub Clubs" in Nevada, and probably other places as well, over time
Single Die: SSS--could it be from the Texas illegal club listed in TGT2?
Thanks, steve
