This collection of exhibit cards shares a common style: the "Personal Greeting" or "Salutation". The specific greeting varies from card to card -- "Yours truly, Best wishes, etc." -- as does the location of the exhibit identification (lower left, LL, or lower right, LR). Some players appear with different teams and there are occasional misspellings. Each card measures 3 3/8" by 5 3/8". The Bob Feller (Yours Truly), Andy Pafko (Yours Truly) and Ted Williams (Sincerely Yours) cards are relatively quite common as they were still being printed into the middle to late 1950s, i.e., basically until the end of their respective careers. The Jeff Heath small picture variation (26B) is differentiated by measuring the distance between the top of his cap and the top edge of the card; for the small picture variation that distance is approximately 5/8" whereas it is only 3/8" for 26A. There is some doubt about whether Camilli #6B exists. An Andy Pafko sincerely yours card is rumored to exist but has never been verfified, while the 50B Pafko is a very tough card since it was printed only in 1960.
