What we have to do is stop believing that cards from the 1940-50s printed on some other kind of paper stock, say like the cards Ted Z collected right out of loaves of Bond Bread are fake or re-prints from some other time, ie, after the 50s; just because they are on another kind of paper.

I believe this was done by people who wanted their cards - on what they thought was the right kind of paper would bring a premium price, or be able to say they have the only true originals, or what they have is rarer than anything else. Or they just believed in what they believed in, and that is why people want to believe that a baseball card on different stock is not from 1947-50s. But as new facts have come to light it has changed our way of thinking.

We can tell old paper stock from modern paper stock. In many different ways, one by a black light. Also by comparing the paper stock to a known 1947 printed card. Yes there were deep fakes printed after 1947-50s on different paper stock, but we can tell them apart by the quality of printing.

Understand, to print the exact image on a card from 1947 you had to have the original photograph, and the odds of a much later print having that original photograph is near 0%. Therefore they would have to copy the original printed card. We can tell when this is done, see the example above. Please understand that cards printing from the 1940-1950s can be printing on many different paper stocks. As I have said it is a (fact) theory, or I should say it is believed that a print run being printed - sometimes hard to change paper stock during a run right in the middle of the run: because they would run out of the supply that had. Therefore they would have to find a replacement stock, because of the shortage of paper in the 1940-50s they would use what they had on hand. You would have one card on the exact same card printed on different paper stock of the exact same image for the same run. John.
