Sharps and Flats; a complete revelation of the Secrets of Cheating at Games of Chance and Skill
An 1894 exposé of gambling fraud by the London magician John Nevil Maskelyne, published by Longmans, Green and Co. for card players, showmen and the curious public. The numbered line engravings show cuffed hands palming dice, holding cups and concealing cards, with stippled shading and letter keys pointing to the hidden move anything needing a clear demonstration gesture.
