Here is something that I found really intereting. This scan is not of a simple punchboard. The whole thing is only on one piece of cardboard with no thickness. On the back it gives the list price of the board, the take in and payout. It was made by Hamilton Manufacturing of Minneapolis and distributed by Frankle Bros. in Youngstown, OH. Given the fact that the cost and payout is on the back of these the only thing I can think of is that these are salesmen samples. Very unusual and I was able to get 4 different ones. Like I said - an interesting day at the flea market.
