Today was the first day I saw the 2009 All Star Jerseys (from the MLB.com shop online) and I was a little surprised at first about how well done they are. I like when the BP jersey's are simple and although they need some flair from home team, they also can use something to connect the two leagues across the nation and they did that this year by using Red and Blue jersey's. As for a throw to St. Louis, the bat on the Cards Jersey is featured on the front and then for both the American League and the National League there is an arch that starts on the dot of the i (in National and American) and ends at end of the team name. The hats are really well done as well as the National League is noted by a N and the American League is noted with an A, which looks nice and simple. Overall, these jerseys look really good.

Just a brief uniform history courtasy of Wikipedia:
These BP jerseys were first used in 1997. Hats were first created in 2007. So this is a recent art.
