Question about Joe Dimaggio. His later autographs in the 80s and 90s do not have the first letter I in DiMaggio. Usually. But as the photo exemplar shows, PSA has authenticated some as real. Dimaggio included the I in early contract signatures. And my theory was he used the I in 1970s signed balls and stopped using it when he started doing shows to save time. I thought the I on later balls meant secretarial or clubhouse signature. Anybody have a theory???
