I've never been much of a pennant collector, but the one featured above and currently available for sale at Worthridge Auctions is too cool not to mention. Check out the auction here.
Here is a 1958 Los Angeles Dodgers pennant from the teams first year in California that includes a fantastic graphic of the LA Coliseum. Best yet, the lovable Brooklyn Dodger "Bum" is seen with a halo over his head and the following caption:
Awesome!
I have no idea what something like this is valued at, but I bet it would look great on the wall of Dodger fans sport cave.
