A brief stroll around a few Moscow galleries and antique shops reveals hopeful attributions (e.g. "Yu P", for Yuri Pimenov, inscribed on a painting clearly not by him) and downright fakes (a Byalynitski-Birulya that was probably painted yesterday). To my eye, and sometimes to my certain knowledge, the London auctions also feature fakes or misattributed works. How do you determine a fake? Not always easy, but here are some signs that, I find, may be present when a fake is offered:
1. The painting isn't very good: it's the sort of thing that, were it not for the claimed authorship, you wouldn't look twice at: the average faker is not as good an artist as those he imitates (there may be exceptions to this rule, I suppose).
2. The price is too low: remember, the faker just wants to sell: if the market price of a Tatlin oil on canvas is $1,000,000+, he's happy to sell for a fraction of that since the whole thing, no matter how sophisticated, only cost him a few grand, max: he appeals to the buyer's greed.
3. There is no proveable provenance earlier than the last few years: the people are all in another country/dead, or it is claimed the work was illicitly removed from a Russian museum (this idea is a variant on the Nigerian email scams).
4. There are signs of newness in the actual product: obviously a top-class faker will avoid this, but it's surprising how many don't. I won't go into detail, but someone with a logical mind will spot some of the errors here quite easily.
5. It's not being offered by Sotheby's or Christies: they aren't infallible, as we all know, but they have the most to lose. S or C are the obvious place to sell a masterpiece, so ask yourself, why aren't they selling this one? Be prepared for all sorts of stories, such as the vendor is "a very private person" and prefers a private treaty sale. How "private" do you have to be to prefer $200,000 to a potential $2,000,000 at auction, if your piece is genuine?
The following are NOT infallible signs of authenticity:
1. A signature. Remember, a signature means absolutely nothing: it can be added. Ditto old labels, inventory numbers on the back.
2. Expertise from an esteemed institution or expert confirming authenticity: these things can be bought, individuals can be pressured, or hoodwinked.
3. Pigment or other scientific tests: any fool faker should avoid using materials whose first use post-dates the presumed date of creation; and in any case many lab reports are simply voodoo bunkum.
4. A catalogue entry or illustration showing a similar work/preparatory drawing etc. As a friend of mine specialising in Suprematism tells me, the fakers are scouring the old catalogues, the Costaki collection etc. and "lost" works by the Russian avant-garde are appearing.
5. The work comes, it is claimed, from a famous collection or is being offered by a very respectable gentleman or lady: even the Great and the Good of the art world make mistakes/need money/get greedy.
Genuine early works by painters of the 1920s - Deineka, Pimenov etc. - sometimes appear, but they are either well-documented in the old literature or have a cast-iron provenance, usually both. I would say that any hitherto-unknown, apparently significant work by the first generation of avant-gardists is 99.9999% certain to be a fake. Look at it, get over it, remember who offered it to you.
