Well, the last edition of this quiz was pretty much a failure. Either I had an off day, or people just don't care about Leaf. I think the latter is most likely. While I thought the Leaf quiz was hard, I think this one is near impossible. If someone manages to get all of these correct without cheating (i.e., using the internet or a price guide...Baseballdad) I will be truly impressed.
That said, your task is to put the cards in order by year WITHOUT cheating. Your answer will be a string of letters starting with 1991's letter and ending with 2007's letter. Winner gets bragging rights as a true Ultra Collector...
