eBay rocks. For all the crap and gamesmanship it’s still a great venue. The last twenty years of it have added some great stuff to my collection. I picked up a stack of H815 Adam Hats premiums—biggest group I’ve ever seen—for ten bucks each. Beautiful issue.
Another one I loved getting for a buck plus shipping was a beater PC that the seller didn’t bother to read. It showed a boxing match with HOFer Billy Papke and was written by Papke with a note and signature. Papke died in the 30s; rare autograph.
Then there is my Burdick-owned E80 Jack Johnson. Wasn’t cheap but the seller didn’t know the provenance.
