New England Artist Brian Campbell has produced dozens of political buttons over the past few years, picturing many of the top political figures of the day. All buttons are numbered, normally with editions of 26 being produced for the 2 1/4" size and the 4" sizes in the last few years. At auction his works have continued to rise in value and are actively sought after by political and pop-art collectors alike. In 2006 a limited signed and numbered edition of 100 books were produced picturing all of Campbell's works up to that point.
