I just got a package in this afternoon from a recent Sportlots purchase. This package had 6 cards that I needed for my set, the most notable was the above Don Sutton. Also among the cards were several high numbers that I needed. It is so tough building these pre-1974 sets because of those high numbers. They seriously carry a premium.
After this package, I need only 19 cards to finish this set. I can definitely see the light at the end of the tunnel on it.
