The listing, 1898 'Cinderella' USA Army Frank stamps has ended.
Up for auction please find two 1898 Cinderella (not officially recognized by the US postal service and not in Scott catalog) "Army Frank" stamps, mint hinged, fine, from a smoke free home.
Here is an explanation of these stamps I found on https://thestampforum.boards.net/thread/1952/army-frank:
"The eminent philatelist and philatelic writer of the1930s-50s, George Sloan, wrote about them many years ago. Seems they were the concoction of a U.S. Army major during the Spanish-American war era. The major was also a philatelist and produced the #116 look-alike "stamps" to dress up the soldiers' free mail of that time. No fraud was intended. The USPO didn't like the idea very much and shut down the operation."
