One of the first Luke Hochevar base cards I remember picking up last summer was this 2005 Upper Deck USA Baseball card from Luke's time on the 2004 USA National Team.
The first one I found was this auto/jersey card, serial numbered 257/275.
Also, I don't know how to classify these autographs. They aren't stickers (which is good), but I don't think they quite qualify for "on-card" as best I can tell, the autographs were signed on a different piece of paper and then incorporated into the card. Maybe these could be "cut" autographs?
While I'm on the topic of USA Baseball cards, I also have these 2004 Upper Deck SP Prospects National Honors cards that feature a piece of authentic game-worn jersey swatches.
Last spring, I was able to watch a USA Baseball game here in Omaha when the USA National Team played a game against the Japanese National Team at Rosenblatt Stadium. And a few weeks before that game, my wife and I watched the USA Women's Soccer team play against the Swedish team at Creighton University. Both games were great fun. What Omaha lacks in professional sports, it more than makes up for in amateur athletics.
