Mr Brainwash
The film-maker at the centre of Exit Through the Gift Shop, who then became the artist.
Mr Brainwash is Thierry Guetta, a French-born Los Angeles clothing dealer who spent years filming street artists, including Banksy, and whose footage became Exit Through the Gift Shop in 2010 — a film that ends with Guetta staging an enormous Los Angeles show of his own and selling out. Whether the whole episode was a genuine transformation or an elaborate joke at the art market's expense has never been settled, and both readings have been good for business. The work itself is unapologetically derivative pop: silkscreened celebrity portraits, spray-painted brand imagery, dripped hearts, broken records and paint cans, produced in volume by a studio team.
Volume is the central fact of this market. Editions are large, unique works are produced in quantity, and the difference between a hand-finished original and a print with spray applied over it is not always obvious in a photograph. Anything sold as unique should carry studio documentation, and the certificate is doing more work here than it does for most artists. Condition matters because much of the output is mixed media on paper or on a found object, and the applied elements — record sleeves, cans, torn paper — lift and shed.
If you own a work by Mr Brainwash
Send photographs and whatever paperwork came with it. The first question is what the work actually is — edition or unique, when, and in what condition — because everything else follows from the answer. A valuation costs nothing and commits you to nothing.
