I picked up #173 Preston Ward a little while ago. He had just gotten out of the military when this card was issued; according to the back, he spent the 1951 and 1952 seasons in the service. It doesn't say if he was ever sent to Korea.
I'm now up to 154/274 (56.20 %). I'm looking at making a couple other purchases soon, so stay tuned. Nothing earth-shattering, just a couple that I've had a moderate level of difficulty tracking down.
