Hello Carlton. I was at Rosemont as well and bought from Bill the image of DiMag changing juniors diaper that is in the upper left part of the scan you posted. As a matter of fact... I'm looking at it right now as It hangs on my bedroom wall ! When pressed, Bill said the photos came from the Mrs. Joe DiMaggio (Dorthy Arnold) estate. Small world.
Here are a few more pieces from the Joe DiMaggio Estate:
DiMaggio's 1948 APBPA Membership Card:

Joe's 1977 Old-Timer's Day suitcase and the original box it was shipped in:
