BELL'S KEYCHAIN PUZZLES - GRAND PIANO

Miniature Interlocking Keychain Puzzles from the 1950s

Since the ready availability of plastics in the 1940s, Keychain Puzzles have been made by several companies. Bell's 1950s range are particularly attractive.

Above is an early working drawing by John Flower who designed several of Bell's Puzzles including this delightful Grand Piano Puzzle.
