Louis Beroud was a fairly well-known artist who did paintings in and about the Louvre. On August 22, 1911, he went to the Louvre to paint the Mona Lisa on the wall of the Salon Carre and saw that it was not there. He asked a passing guard where it was. The guard shrugged and said "Probably being photographed." Several hours later when La Joconde had not been returned, Beroud saw the guard again and asked when the masterpiece was going to be returned. The guard was concerned that the Mona Lisa had not been rehung. He immediately went off to the photo studio to see. He came back very agitated: the photographers did not have her and hadn't seen her. She was missing.
This painting is dated 1911. I'm not certain but it may be the painting that Beroud was working on when La Joconde was stolen. (Courtesy of Eileen White)
