It's not the sort of thing you generally see in a museum: a comfortable easy chair, a working TV set turned to an afternoon talk show on which "Keeping Up With the Kardashians" mom Kris Jenner is making salsa.

But this unlikely arrangement is, in fact, a work of art, on view as part of the Hammer Museum's Robert Heinecken retrospective, "Object Matter." The longtime L.A. artist, who passed away in 2006, was known for his pioneering use of found photographs in sculptural assemblages and vast wall installations. He was also known for undertaking guerrilla actions, such as surreptitiously printing images into new editions of "Time" magazine and then returning the copies to the newsstand. (San Francisco's Museum of Modern Art has an example.)
