“Last week, Christie’s auctioned off 74 pieces from the collection of the Swiss art dealer Pierre Huber…The sale netted almost $17 million and set auction records for Mr. Kawara, Jim Shaw, Paul McCarthy, and Albert Oehlen. But some of these artists and their dealers say that for years Mr. Huber claimed he was building a collection that would end up in a museum. On that basis, he acquired works, sometimes at discount prices, that he couldn’t have otherwise.”
