Yeah it was clear from the context. What I was pointing out is it wouldn’t be odd for Bansky to cooperate with the institution. He’s got a habit of colluding with gallery owners for things like this.
And I though I was clear that Sotheby’s apparently inspects things like that anyway. It doesn’t matter that its an artists frame, or the piece was from the artist directly. Or the artist instructed them not to inspect it. The reputation is that that Southeby’s inspects it anyway. Above and beyond typical dealers and auction houses. Southeby’s thing is very much carefully authenticating everything they put up. I don’t think it likely that this could have been slipped through if they weren’t directly involved.
