The Vanishing Leprechaun is a puzzle that became popular in the late 60s and early 70s. There are 15 leprechauns in the top image, but when the two cut-out pieces are swapped over, one of the leprechauns vanishes. The illustration was drawn in the late 60s by Pat Lyons and sold in magic and novelty shops. Illustration: Pat Lyons Share on FacebookShare on Twitter
The earliest version of the leprechaun-style vanishing puzzle that I have been able to find is The Magic Egg Puzzle, from 1880. The card is cut into four pieces, and they can be rearranged to make 8, 9 or 10 eggs. I printed out a copy of this and it really is very ingenious. Try it! On the back of the card is an advertisement for Wemple and Company, a US firm. It was common for promotional flyers to have puzzles like this on the back.

In 1907 Theodore L DeLand Jr, an amateur magician from Philadelphia, copyrighted La Mystérieuse. This version was used as a business card by the American magician John Percival (1888-1974).

Jim Holdaway, the British artist most famous for illustrating the Modesty Blaise comic strip, drew this fantastic vanishing puzzle of pin-up girls in the late 60s. He was commissioned by John Henley, the London magician and magic entrepreneur, who used to sell a similar puzzle from Austria. Illustration: John Henley Share on FacebookShare on Twitter
John Henley, who has since moved to Canada and become a movie actor, told me he sold thousands of Vanishing Lady puzzles in the 60s and 70s. Illustration: John Henley Share on FacebookShare on Twitter
Another Swedish variant, with apes, from the 90s. Who knew the Swedes were so into geometrical puzzles? Image courtesy of the Lilly Library, Indiana University, Bloomington, Indiana Share on FacebookShare on Twitter
