I made two separate tiles. The top features cards from my team sets, cards from the different brands of complete Cubs sets that I've got. The bottom tile has the cards from my player collection. Between the two there are 280 cards. A search at Beckett returns a list of 735 Ernie Banks cards. I guess I've got a ways to go!
And by the way, as I was previewing the post I realized that I included a card of Willie Banks. I'm not ambitious enough to make the tile over, so I'll let you play Where's Willie instead.
