President, Dwight David Eisenhower signed Executive Order No.10834 on August 21, 1959 and had printed in the Federal Register at 24 F.R. 6865, pursuant to the law, stated that: "A military flag is a flag that resembles the regular flag of the United States, except that it has a yellow fringe border on three sides."
Gold fringe seems to indicate some sort of military relevance:
