Campaign button

In the United States, political buttons date as far back as President George Washington.

Campaign buttons bear some similarity to bumper stickers, which are also used for political and other promotional messages.

The first mass production of metal buttons dates to the 1896 William McKinley campaign for president with "celluloid" buttons with one side of a metal disk covered with paper (printed with the message) and protected by a layer of clear plastic.

A lithographed button may fasten with a pinback or with a metal tab which folds over a lapel or pocket.

The most valuable example is believed to be a rare campaign button from the 1920 presidential election showing the likenesses of candidate James M. Cox and his running mate Franklin D.
