In the earlier days of ebay, I was fortunate enough to win what I think was a full Dodgers team set of signatures, circa 1977-78. These were apparently from the plaque company and were somewhat different from the ball company contracts. Mine were just the signature examples that appeared to be cut off the original contracts. I also have a Glenn Burke ball contract. I used both types of signature example sheets to show his signatures in this blog entry.
