I sure everyone is aware of issues like W554 and the '40-'50s exhibit cards that carry a back stamp identifying a specific product or retailer. However there are several other issues that I have seen/obtained stamped (usually) by a specific retailer.
For example I have found the 1949 Speedway issue with 5 different Detroit area gas stations stamps on the back. Also the 1952 Fleetwing Gas Issue in Cleveland exists with various back stamps. The 1939 Father and Son Philly issue likewise has several different store stamps on the back. The 1926-29 Exhibit issue exists with a Connecticut Barber Shop offer of free cards-nicely printed. Even the 1947-49 Jack Robinson Bond Bread issue has been seen with a store stamp. Interested in hearing of any such examples you may have run accross. I can quote at least 8-10 others. Interested any info and also purchase of any I nned.
