My Roy Campanella PC is nearing the point I can say it's almost complete. A few cards are still missing, with that glorious 1952 Topps High-Number the most obvious one I may or may not have any time soon, but 1953 Bowman Color was also noticeably absent for far too long. A recent eBay win rectified that void.
Campy is quite a bit more beat-up than I had thought based on the seller's poor picture in his listing. I had pegged the card to be in good condition when I bought it but it's definitely poor-to-fair now that I have it in front of me.
