I was at a yard sale today and the lady had some old Las Vegas dice. They were pricey so I couldn't buy any but, she was nice enough to let me take some pictures of some. She had several two packs of dice but, never opened them. She said her uncle was in charge of the games at several casinos back in the 1960's. She said he worked in Vegas for 25 years or so. His last name was Garrett. At lot of history in those dice I guess.
