One of the most frustrating things about eBay is losing an auction on an item you really want. Below is an example of one of these auctions. It is a 1933 W574 Luke Appling card that I needed for my set. These cards are really tough to find and features players from the Midwest. This may account for its rarity since it was probably a regionally issued set.
Damn you Leon! It might be a year or two before I run into another one. I need just 5 more cards.eBay Auction Link:
