Later magic
Later Magic, a 1904 magic handbook by Professor Hoffmann published by E.P. Dutton in New York and George Routledge in London, aimed at amateur and professional conjurers learning sleight of hand and apparatus tricks. The four line drawings show simple props: a tilted oval tray with a slot and two holes, a box or pouch marked with dotted circles numbered 1 and 2, a cylinder with a wire loop and a hidden ball, and a flat oval ring. A designer could draw on their clean, schematic outline style for diagrammatic, instructional linework.
