In the context of Campbell's Soup Cans, analyze the Unauthorized versions of the Variations.
In 1970, Warhol entered into a collaboration in which he facilitated exact duplications of some of his 1960s works by providing the photo negatives, precise color codes, screens, and film matrixes for European screenprint production. Warhol signed and numbered one edition of 250 before subsequent, unauthorized, unsigned versions were produced. The unauthorized works were the result of a falling out between Warhol and some of his New York City studio employees who went to Brussels where they produced work stamped with "Sunday B Morning" and "Add Your Own Signature Here". Some of the unauthorized productions bore the markings, "This is not by me, Andy Warhol". Art galleries and dealers market "Sunday B Morning" reprints of several screenprint works, including those from the Campbell's Soup can sets.
