Yup... Mike H and I were both marveling at that one, Adam...
He and I both have the matching Cubs Pennant from that '45 World Series, and are both envious of your acquisition (Ok, I shouldn't speak for Mike but safe bet he is as jealous as I am...)
Yours is just a gem on 4 levels...
It's a never-seen variation
It commemorates a very important year
The "font" matches the Cubbie version to a tee
The condition is amazing- especially given its age
I know it didn't come cheap, but in retrospect, I think you stole it. I was surprised that the Cubs pennant went for more... probably just a result of the huge number of Cub fans out there. There's no comparison in terms of rarity.
Just a wonderful pickup
