Reddin and Kienholz began their creative collaborations the same year they met. Their first work together was The Middle Islands No. 1, now in the collection of the Louisiana Museum of Modern Art in Humlebæk, Denmark. Ed Kienholz continued to receive sole credit for these collaborations until 1981, when he publicly announced for the first time that all works after 1972 should be retroactively credited instead to "Kienholz", in collective reference to both Ed and Nancy.
