BEFORE THEY WERE FAMOUS offers a rare glimpse into the working studios of Pop Art giants Andy Warhol and Robert Indiana, two artists who shaped the direction of American art in the 1960s. This is the collection’s New York City debut.

William John Kennedy shot the images of Warhol and Indiana, which had been forgotten in storage in the photographer’s studio for over four decades.

The photos are available as a limited edition collection of silver gelatin and chromogenic prints.
