I was given a 48 star flag many years ago, and I am wondering if anyone knows the approx. Value and Age. Or any information at all about it. Unfortunatly I have no history on it. Size: 5x9.5 Brass Grommets individually sewn stripes and stars. reinforced corners Cotton This is what it says VALLEY FORGE FLAG CO. SPRING CITY, PENNA 5 X 91/2 FT COTTON What I do know is that it was roughly made around WWII It may be a Casket flag. But what sticks out to me is that it Reads PENNA instead of PA. Not sure if that means anything? Thank you so much for any help.
