I sell four different brands of US flags, but two of the oldest manufacturers, one being Annin and another being Valley Forge, both heavily imply itâ€™s their flag on the moon. I found this fascinating, so I called each manufacturer and asked why this was and the answer I got was thisâ€¦"the flag on the moon could be either companyâ€™s, the Apollo had both flags on board when they left. Mr. Armstrong has been quoted however that before they left someone went to Sears and bought some more flags and had them modified. Since Tangâ€¦ NASA will no longer endorse a brand." I guess it doesnâ€™t really matter, but I find it interesting.
