The new book from the National Comedy Center and Smithsonian Institution, Funny Stuff, How Comedy Shaped American History (Rutgers University Press, 2026) would naturally include a portrait of the Marx Brothers, who were among America’s most popular comedians of the 1920s to the 1940s. This portrait was made in 1948 for Collier’s magazine. Karsh wrote, “I hope that I have captured in my photograph the spontaneity that resulted from the three brothers’ inability to be still for even one moment.”
