This may be the problem....
(from article above)
"In 1949, 32 of the cards were given a new distinctive “AN EXHIBIT CARD” mark, and team cards were added for the first time.
Eddie Waitkus was reissued with the “C” for Cubs airbrushed off his cap, so actually 33 cards were identifiable as being issued in 1949. The team cards first appear in this year."
I may have added it to the checklist because of this note..... I will remove it until I actually see another. thanks for pointing this out, I am far from an expert in Exhibits
PS. the uniform was airbrushed, not the hat, .......so thats another error in the article.
