We left off last Sunday with Frank Stella contacted, and planning to visit Sotheby’s to authenticate his painting the next day. Sotheby’s called me after the meeting.
“Frank says it is not his.”
They explained that an artist can disavow a work if he is not happy with it, and it will be deemed “not his” even if he did create it. (Our seller had mentioned that Stella gave it to his girlfriend partly because he was unhappy with it.)
