Pssst. if you like that I've got a swell bridge in Brooklyn I can sell to you. It's only a little used and I can write a nice letter for you saying it is all yours once you send me your money. Here is a photo of it.
Kidding aside - there is zero provenance with that thing, and as others have said the fabric itself is not even half convincing.
Whether or not there are other bidders tells you nothing about whether it is real. There are plenty of "marks" out there willing to place their money on such things, and sometimes the sellers put in shill bids - though there is no way to tell if that is happening on this lot.
