Art insiders say Russian billionaire Roman Abramovich is not the mystery buyer who snapped up a Francis Bacon triptych painting for a record-smashing $142.4 million this week.

There have been reports that Abramovich — a noted Bacon-lover who certainly has the cash to spare — was the man who really snapped up the work at Christie’s postwar and contemporary art sale when Acquavella Galleries bought it on behalf of a high-flying client. (After all, Abramovich will need to decorate his new $75 million Fifth Avenue townhouse with something. And he previously purchased a different Bacon triptych for $86 million.)

However, a source close to the oligarch told us, “No, it’s not him. Keep guessing,” while a different source familiar with the transaction said, “I’ve never heard Roman’s name mentioned” as a potential buyer. William Acquavella’s gallery has been incredibly tight-lipped about the acquisition, and Abramovich’s reps didn’t comment. Rival dealer Larry Gagosian has said he went as high as $101 million in the six-way bidding war for the Bacon.
