Description: "Thousands of people have had fun with codes. So can you. Here is an easy-to-follow, step-by-step guide to secret codes – how to make them, use them, and break them. Learn about alphabet codes, ciphers, code wheels, secret languages, number codes and many more besides. Know how to make all kinds of invisible inks, many from things found in every kitchen – sugar, salt, milk, vinegar, washing soda, even Coca-Cola!"
Illustrated with numerous b&w sketches and diagrams.
Pictorial covers have some minor edge wear. As is to be expected in a cheaply produced paperback fast approaching its 40th birthday, the pages are tanned, and there are two negligible closed tears to the edges of pp. 52 and 54. Otherwise all pages are in very good, unmarked condition: free from foxing and very tightly bound.
Measures 19 cm × 12.5 cm (7.5″ × 5″). Large 12mo. 86 pp.
