Today a purchase arrived that I'd forgotten about when I gave an update yesterday: #219 Pete Runnels. The player on the card is actually his teammate Don Johnson; somehow the name got switched so the card was printed with Johnson's portrait.
This brings me to 74/274, or 27 % of the set. The Matthews I'm waiting on will make it 75/274 (27.37 %). Only 199 more to go!
