Bump Elliott Exhibit card question
 

I'm collecting signed Exhibit cards and 2 years ago I came across a Bump Elliott Exhibit card that I got signed through the mail. Does anyone know anything about this card? It's not listed as one of the 59 cards in the 1948-1952 Exhibit W468 Football set in the Standard Catalog - so was it part of a multi-sport Exhibit "set"? Is anyone aware of any other Exhibit cards of football players not listed in the 59-card set?

Thanks!
