In going thru a family estate, we have found a 48 star flag that is 6'x9'. The stripes are sewn, but the stars are printed. I'm pretty sure it's cotton. There is a grommet at the top and bottom only. Stenciled on the border in black block letters is "H.CO." followed by a 5-cornered star. There might be a spread-wing eagle at the beginning, but it's pretty smudged, so not sure. There are no other identifying marks. One family member vaguely remembered being told that had something to do with having been made for a federal Health Care Organization but couldn't be sure. Can anyone tell us anything about it?
