Artists Andy Warhol and George Klauber kick back in a New York City studio circa 1949. "Artists Unframed" author Merry A. Foresta plumbed the Smithsonian's Archives of American Art for candid images that show revered modern artists like we're not used to seeing them. Whether they're creating, clowning around with friends or just surrounded by loving family, these artists' private lives are bared for the camera.

Abstract artist Jackson Pollock adorns one of his famous giant canvases in his studio in 1950. The kinetic shot captures the athleticism of Pollock's painting style. The black-and-white film does not allow a look at his color scheme, however.

Dorothy Dehner and David Smith are shown here circa 1928, the year they were married. Each was educated at the Art Students League of New York. Dehner told the Archives of American Art about Smith: "He was terribly interested and very vital, and I remember, as a reaction from his spats-and-derby kind of dressing, he would go home and get in to a pair of old slacks and some things he called romeos -- they were great, flapping bedroom slippers with rubber sides, you know. And he would wear those to the (Art Students) League, and this made him distinctive. ... He was terribly cute and very, very tall and skinny and quite a personality in the group there."

This photo of Diego Rivera and Frida Kahlo was snapped at her family's home in Coyoacan, Mexico, in the early 1940s.

Kahlo was often bedridden due to health problems and surgeries resulting from an accident she suffered as a young woman.

Pablo Picasso holds a fluffy puppy while posing for a snapshot with his daughter Maya circa 1944. The photo was likely taken in Paris, where Picasso lived during World War II. Maya would have been about 9.

Here's a more recognizable Warhol palling around with Yoko Ono and John Lennon in June 1971. Ono was an avant-garde artist as well. "Is this a demonstration of pop music embracing pop art?" Foresta asks.

Alexander Calder, famous for his abstract paintings and mobiles, wrangles toy bulls on a rooftop in Paris in 1927. Calder lived in Paris between 1926 and 1933. "During these years the young American created one of the most beloved works of modern art, a miniature circus that included more than seventy small acrobats, tightrope walkers, and performing animals," Foresta wrote.

Gertrude Abercrombie kisses an unidentified individual in this photo-booth snap circa 1945. Abercrombie, who was dubbed "the queen of the bohemian artists," painted from a studio in Chicago. She often produced self-portraits in a surrealist style.
