They say imitation is the sincerest form of flattery. But in the case of one artist, some critics disagree. American artist J. Seward Johnson is known for his sculptures inspired by famous paintings and photographs. One of these works—a supersized sculpture based on a 1945 photograph of a sailor kissing a nurse at the end of World War II—is causing debate in San Diego. Supporters praise the 25-foot-tall work, Unconditional Surrender, for its depiction of a moment in American history. Critics say it is unoriginal because it doesn’t significantly change the intent of the original photo by Alfred Eisenstaedt.
