Don't be fooled, folks. Potter & Potter's June 23rd auction may be billed as a Gambling Memorabilia sale, but there's plenty of material in the auction for magicians to love. From a first edition of Erdnase to holdouts, crooked dice and juice joints, there's likely something of interest for magic collectors. In fact, the cover of the auction catalog features a gambling device used by a famous magician - Harry Anderson. It's a holdout made by Owen Magic Supreme of California, and used by Anderson on both Saturday Night Live and The Tonight Show with Johnny Carson. Take a look at the complete catalog, or watch a video of Anderson performing his holdout routine on Youtube.
