I just obtained a 48 star flag with stars arranged in evenly spaced rows. There is no marking other than 5' x 9'6". The fabric is lightweight, wide weave. From reading the forums I have concluded: 1) It is the size of an internment flag 2) It is likely cotton and perhaps a WWII era 3) With no maker marking it is impossible to know much of anything! 4) There were maybe a half-million of these from various makers during the WWII era I would also like to note that the stars are sewn onto both sides. There are two brass grommets. If you can contribute to my investigation... please jump in! I'm a new collector and thought this would be a great start!
