My grandfather recently died and I was cleaning out his basement and came across an old embroidered 48 star flag stenciled with US Ensign No 6 Navy Yard New York 1916 down the hoist of the flag. The flag measures 17' x 9' so is in keeping with the sizing chart for the No 6. My question is if anyone can give me any info or history into the flag, what it is made of, I would imagine wool. How many were made during this time, where were these flags were usually flown. What would be the value of this flag? Finally i'm looking at hanging it horizontally along my wall in my basement, any recommendations on hanging it, I don't want to damage it in any way of course. Thanks.
