“At what point did acquiring performance art switch from owning objects associated with the actions, such as videos and photographs, to possessing the “idea” behind the piece? Berlin-based artist Tino Sehgal has evidently turned collecting criteria on their heads. He sells his performance art pieces by means of verbal transactions in the presence of a lawyer with no written contract. Instructions on how to re-enact his works are delivered literally by word-of-mouth, with collectors under strict orders never to photograph or video his “constructed situations”. Yet they sell in editions of four to six for $85,000 to $145,000 each, according to The Art Newspaper. “
