Doug, that is a fantastic Dodgers Pennant Collection!
Some incredibly rare ones there... some of which may not surface again in the next decade. It would take forever to amass a collection like that today.
Domer was right however, about the one with the Pinbacks in it. The Pins are legit, but that particular pennant is indeed a 1980s reproduction. If you look closely, you'll see the felt is different, and there are probably a few of them on eBay as we speak. Seems like half of the eBay Sellers properly describe them as Repros, and half just let it slide.
But all the others are 100% original and magnificent. Thanks for sharing those incredible treasures with us!
