Thanks to Naomi G. for that reply. However, I had a Zip-Loc bag in 1961, although it was not called that, but was a marketed gimmick for magicians that I bought from a firm in Pallisade, New Jersey, Ken Allen Products, at that time. I won't mention its name which could possibly reveal a magic secret. I suspect that the owner may have got the idea for a magic application from seeing such a bag used for industrial purposes before it was released in the consumer market subsequently. Does anyone know if such a bag was, indeed, used in this sector, initially, or know of any company or individuals using this type of bag at this early a date? My thanks to anyone who might be able to help.
