Federal guidance based on American Legion conferences.
Congress passes Public Law 77-623, Chapter 435 – U.S. Flag Code. The federal guidance for rules on the display and care of the U.S. flag are nearly identical to those established by The American Legion flag conferences of 1923 and 1924. Many states, municipalities and schools have already by this time enacted flag codes, based on the Legion conferences and massive promotions through the years, by the time Congress codifies them in federal law.
