Roy Lichtenstein [SEP] Roy Lichtenstein Foundation
After the artist's death in 1997, the Roy Lichtenstein Foundation was established in 1999. In 2011, the foundation's board decided the benefits of authenticating were outweighed by the risks of protracted lawsuits. In late 2006, the foundation sent out a holiday card featuring a picture of "Electric Cord" (1961), a painting that had been missing since 1970 after being sent out to art restorer Daniel Goldreyer by the Leo Castelli Gallery. The card urged the public to report any information about its whereabouts. In 2012, the foundation authenticated the piece when it surfaced at a New York City warehouse. Between 2008 and 2012, following the death of photographer Harry Shunk in 2006, the Lichtenstein Foundation acquired the collection of photographic material shot by Shunk and his János Kender as well as the photographers' copyright.
