How to Turn a Bank Note Upside Down
This page attempts to record what is known about the origin and history of the folding sequence that can be used to turn a bank note upside down. Please contact me if you know any of this information is incorrect or if you have any other information that should be added. Thank you.



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.



As 'Upside Down' in 'Party Lines' by Robert Harbin, which was published by the Olbourne Book Co in London in 1963.
