These "Slate" colored (or lack of background color) 1949 Bowmans are not proofs.
They are simply cards that did not have their final color printing phase. I wrote an article on these in the VCBC magazine
several years ago. I list the possible cards in this set that can be found with "Slate" backs. I have collected these since I
was a kid. This may seem unusual, but I first found these color errors in 5 cent packs in 1949. And, they were all perfect
Factory-cut cards.
Most, however, are found hand-cut from 36-card Bowman sheets.
I have 19 of these from the Lo# series (#1-144) and 25 of them from the Hi# series (#145-240....plus the 12 variations).
I'll continue to search for them....but, I don't expect to complete a set with "Slate's".
