As far as I know John Bittel and Rick Olsen are the guys who wrote the book on Dice,literally.I have done business with John recently and asked him about his dice and he says they are all original.I have met Rick Olsen at the convention and he and his family are probably some of the sweetest most genuine people I think I have ever met.I bought quite a few really nice dice from him as well.I have posted them on the board and have gotten comments about them looking to good and possibly second issue,this is one question I asked John and he says"no" all original.Some dice have never been used,I guess thats why they look so good.I am no dice expert but I have bought them from the experts and feel fortunate enough to have picked up some rare and beautiful dice to accent my chip collection and casino memorabilia.So I have put these pictures of one of their dice booklets here for you to see,I hope you enjoy and you can contact them with any questions or concerns. I am glad others are picking up some as well and are asking questions as I have,we need to be informed and learn.It is a beautiful part of the casino collectibles,Torrey
