I recently won a rather large lot of MLB Showdown cards on Ebay about a week ago. The majority of them aren't cards I need at all, in fact I need very few considering there are 40+ sets ever printed.
The main reason I purchased this lot was due to a rare promotional card of Luis Gonzalez from 2002. The set this card comes from is known as the Showdown Stars card set. I already had the other 4, and Luis Gonzalez was the remaining card for the completed set.
The binder these all came in was stuffed full of cards, with more than 1 of each player in the same pocket. I happened to pull out the Gonzalez to take this photo, and it just so happens, this lot contained two of these promos, crazy luck.
