Eric Eichelkraut (goudeyhunter)One other theory I've concocted is, like many other vintage issues, the squares were possibly glued or stuck to a Colgans advertising board, that was placed near the candy in stores. This would explain the rough backside found on so many of the existing examples, and would have also allowed kids/collectors access to them. Whatever the real story may be, I don't believe that these are proof cards, there are too many of them in circulation. They may not even be Colgans related..as many have pointed out.
Another question regarding the squares, are the pictures featured on them the same as those on the Colgan chips? I don't have any to compare, just wondering if anyone had compared the two?
Thanks for the responses!
