In 1922, the eagle badge replaced the earlier versions. The Postal Laws and Regulations initially specified that the words "U.S. POST OFFICE" would appear along the top of the badge and that the name of the Post Office and state would appear along the bottom. By 1960, the Postal Manual specified that the words "LETTER CARRIER" would appear along the bottom. The pin closure (top row, right) was replaced by a tack and screw post closure in 1968.
