Shown to Frank Lobdell during anĀ August 1992 interview by Nancy Boas, Lobdell remarked that the painting was done in 1948 in a painting class taught by David Park. Lobdell said, “I like it very much.” He added that he was working in a room with William Ivy and John Hultberg. He commented, “I think I had been looking at Slow Swirl by the Edge of the Sea— a work by Rothko at the S.F. Museum at the time. You can see the Rothko in the shield.”
