When you hear the words 'Outsider Art' in Chicago, Carl Hammer is the first name that comes to mind. He has discovered a number of unknown, untrained artists and exhibited their work with his signature style and presentation. He is recognized nationally, not only as an expert in outsider art, but for his assemblage of mainstream contemporary artists as well. Among artists whose work is shown frequently at Carl Hammer Gallery are: Gregory Warmack (better known as Mr. Imagination), Michael Noland, Hollis Sigler, Bill Traylor, David Philpot, Lou Cabeen, Henry Darger, Lee Godie, David Sandlin, Jerry Smith, John Snyder, Fred Stonehouse, Eugene Von Bruenchenhein, Ken Warneke and Joseph Yoakum.
