Now if only George had urinated into a cup, and put the picture into the cup, THEN IT WOULD ART. /S
See: https://en.wikipedia.org/wiki/Piss_Christ
Piss Christ is a 1987 photograph by the American artist and photographer Andres Serrano. It depicts a small plastic crucifix submerged in a glass of the artist's urine. The piece was a winner of the Southeastern Center for Contemporary Art's "Awards in the Visual Arts" competition,[1] which was sponsored in part by the National Endowment for the Arts, a United States Government agency that offers support and funding for artistic projects, without controlling content.
I should think all George would have to do is not sell the painting (take it off the market) and do a new one based on memory or a non copyright picture. End of story.
