As I've said before, I'm not much of a pennant collector, but when something catches my eye I can't help but share it. Case in point, check out the two vintage Brooklyn Dodger pennants currently offered at auction at Inside the Place Collectibles.
Above is a fantastic 1955 World Series pennant that stretches 28.5 inches long and features the facades of both Ebbets Field and Yankee Stadium. (Auction Link) As you know, this represents the only championship series the team from Brooklyn won, and as you can imagine is highly sought after by collectors. As of this posting it is already at $550.
