Orlando Cepeda signed each of them through a private signing that an SCN contact set up.
I created a checklist of the Greats of the Game cards that I have. Of the 107 cards, I have 36 signed. I was surprised to see how many of the certified cards I have signed, and I haven't counted those in this count. I also regret not having sent some out to players I used to send to but have since passed away, such as Bob Feller and Phil Rizzuto.
I do have a few really nice ones including Duke Snider, Yogi Berra and Rod Carew.
I sent out four requests yesterday, including a 52 Topps, a couple 54 Topps, and a 65 Topps.
