A paperfolding paradise
The website of writer and paperfolding designer David Mitchell
|Turning a Bank Note Upside Down|
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.
