Hi - I've recently acquired a very unusual 48 star flag. Unlike the usual layout of star, it has a large center 6 pointed star in a 13 star circle and a 22 star outer circle around that and 3 stars filling in each corner. It appears to have had considerable wear, but I am not sure if it ever had an official purpose. I can't find any information of an official flag with larger number of stars that was not in the matrix formation. Any ideas?
