Rare original large format (22" x 28") 1970 U.S. Mail posterboard promoting use of zip codes with cartoon character "Amy". The character of Amy was introduced by the Post Office in 1970 to supplement the classic "Mr. Zip" character, but never caught on. Poster is in good overall condition with bold colors, but shows wear from storage including some moderate yellowing and occasional bruised edge/corner. Poster is printed/mounted on thick cardboard stock and measures 22" x 28". Ships flat. Multiples in-stock - please note condition may vary very slightly from sample shown in photo.
