GeorgeHere's a red date stamp on one of my T206 cards which looks to be September 24, 1909. I do have a few others with other odd markings on the back so if I get a chance will post those as well.
Barry, I also have a few cards with Elias written on it and tend to recall one ebay seller who recently had several T206 cards up for sale with "Elias" written on the back. I have no idea of the history.
Has anyone considered documenting some of the stamp backs on the T206 cards? It would be a massive undertaking but would not be surprised if someone is already looking into this. I'd be very interested. Thanks.
