Nicholas Kahn and Richard Selesnick are a collaborative artist team who have been working together since the early 1980s. They work mostly in the fields of photography and installation art, specializing in fictitious histories set in the past or future such as documentary-style panoramic and square photographs that combine absurdist fantasy and bogus anthropology, elaborately crafted artifact, costumes and sculpture, often constructed of unlikely materials such as bread or fur, painting and drawings ranging from large scale works on plaster to pages of conceptual doodling.
