Although he was an atheist and despised feigned religiosity, Keinholz carefully preserved an anonymous store window shrine discovered in Spokane, Washington. Calling this found outsider artwork "The Jesus Corner", Keinholz exhibited it in a Spokane museum in 1984, and then showed it at the San Francisco Museum of Modern Art. Ten years later, Keinholz insisted on selling it at a reduced price to the Missoula Art Museum in Missoula, Montana, to ensure that it would be on view in an environment he felt comfortable with.
