1941

The earliest publication of this effect that I know of is as 'The Curious Fold' in 'After the Dessert' by Martin Gardner, which was published by Max Holden in New York in 1941.

This effect also appears in 'Willane's Wizardry' by Willane, which was pubished by ARCAS, in London, and has a foreword dated 1947.
