I recently added a fairly big piece to my 1972 Icee Bear PSA 8 project. A couple of the players will cost me far more than I aim to spend on average but because it's only a 20-card set I'll only have to depress my wallet a couple of times. Thankfully it'll be one less time than I anticipated at the outset as the below card came much cheaper than I ever thought it would.
This beautiful Kareem Abdul-Jabbar -- card number 1 in the set -- appeared as a BIN on eBay for what seemed like a really low price.
