Cigarette cards were a form of trade card, originally functioning to reinforce cigarette packets but quickly becoming collectable. Companies produced themed sets such as these as promotional tools. Carreras was a London tobacco company. Their 1937 series of 50 cards of ‘Amusing tricks and how to do them’ feature cartoon illustrations with brief descriptions on the reverse. Cards issued by Fry’s Ltd. are shown in an album. The series of 50 ‘Tricks and Puzzles’ cards, issued in 1924, have illustrations of tricks and simple instructions on the back.
