Does anyone know the date that Jerry Andrus first made and sold the Linking Pins?

I can't directly answer your question, but Andrus's book Safety Pin Trix appears to have been printed in 1955. (This is according to a listing at http://www.abebooks.com)

That's what I thought, just needed to get a second opinion, thanks. I sold off most of my books, hence unable to check.

My pleasure, Pete. Are you working on something with pins?

Not really... what I am working on (finally) is my "History of the Linking Rings" book. and since Andrus' pins linked....

I have the book in front of me now and here's the copyright info.

Originally published in 1956, then reprinted 1972 and 1990. Copyright 2006 Jerry Andrus & Chazpro. Originally published by JA Enterprises. Revised edition published with permission by Chazpro Magic Co.

Hope this helps.

Thanks much
