Controversial feminist artist Betty Tompkins, of ‘70s-era Fuck Paintings fame (extreme close-ups of couples having sex, taken from vintage porn stills) is being celebrated in a new exhibition at FUG (Foundation University Gallery) in New York City. Real Ersatz is on view through October 18 and will feature new work from the artist that continues to explore medium, scale, technology, and more. Tompkins is joined by a number of artists whose works have stirred debates and, in some cases, legal action regarding obscenity and the public. Here are just a few of those creators. Feel free to share your personal favorites, below.
