Hey there, I've acquired a very old 'looking' 13 Star Cowpens flag...The main thing right off the bat is it appears to be a vertical display flag being the square is in the right corner. I can't find nearly any information on the identification of a Cowpens flag as the only thing I'm able to find is the simple history of the Maryland 3rd Regiment and the flag itself. Could this have been a possible battle flag? Were vertical flags made in the same era? It seems to be of very old material and contains possible blood stains. Any help would be greatly appreciated! Thanks!
