My uncle gave me this 48 Star Flag. The stars are embroidered. The red and white stripes are individually sewn together. The flag appears to be made out of cotton. It has a tear that has been repaired. Usually all flags have brass grommets. This one appears to have steel or aluminum. Which seems like it might out it in the WW2 era when they saved brass for ammunition. My grandfather was in the Navy during WW2 and the Korean War. From what I can tell official US Navy flags have marking stating such. I also read where that kinda went to the way side during WW2. Nobody knows where it came from or the history other than it was in my grandfathers belongings.
