Circa 1958, the ad from Richard Himber stated “A gorgeous simulated leather attache case, hand-stitched which carries your act and switches slates, cards, magazine, etc. but here's the payoff. It is the closing trick of your act wherein a spectator predicts in writing what key will open it even though he has never seen him. No stooges”.

This was a fairly expensive item from Mr. Himber and includes illustrated instructions and an envelope of Mr. Himbers containing all the keys to the attache case. Condition very good.
