I do not think the stamp was used to validate any redemption. I would go with the theory of the factrory stamp needing to be on the card. Why else would every tobacco issue have the factory info? I have seen quite a few high grade ones with the stamp as well.
The B. E. Thompson card states "save your B.E. Thompson cards" I do believe they were part of a prize program.
B.E. Thompson was the league commissioner.
