I recently won a group of 3 used NY Yankees postcards on the 'Bay. There was no mention of any autographs on the three, but you could see from the photos that the Joe Collins had signature on the back.
Once I got them in hand, I could tell that the Collins was authentic, and also found that the Rizutto was addressed in his hand. No autograph, but the address was clearly written by him as it has his telltale letter formation for the two 'B's in 'Brown' and 'Bronx' that he uses for the 'P's and 'R's in his name. I could not determine if the addresses on the Bauer and Collins were in their hand or not.
