Steve McQueen artworks acquired by Amsterdam museum
The art world might present itself as a refined elite above the vulgarities of consumer society, but in fact it is just as intoxicated by the razzle-dazzle of celebrity culture as the readers of Grazia.
Fame in the art world has the same affect as fame in the rest of society: it raises the value of an individual's stock. Which, when it comes to an artist, is art.
When Steve McQueen won the Turner Prize the value of his work will almost certainly have risen. To be the first artist in history to also win an Oscar - working in the same genre (film) - will inevitably further increase his prices.
His newly acquired international celebrity status is also highly valued by museums, who are desperate to attract a large, broad audience. The popular appeal of being able to own and show a film by a famous movie director is likely to tick several institutional boxes.
Banksy's Kissing Coppers sold at US auction
If you happen to own a wall which Banksy has used as a canvas for one of his art works - I should imagine you are perfectly within your rights to hack it out and sell it.
The issue is more with the buyer who is complicit in owning a piece of work whose spirit and intentions were to be a site specific, social comment in the public domain and not designed for a private collection in a smart mansion or white walled modern art gallery.
George Clooney on tackling stolen Nazi art in The Monuments Men

George Clooney was so inspired by the story that he decided to make a film about it.
National Gallery acquires first US artwork
Tate and the National Gallery have an agreement that is renewed every decade that sets the parameters of each institution's collection strategy to avoid overlap and competition. The line has hitherto been drawn around 1900, the point at which the National Gallery hands the story of Western art over to Tate Modern.
The acquisition of the Bellows blurs that line as it was produced in the second decade of the 20th Century, which has always been very much Tate territory. It raises the prospect of the two national galleries competing for certain paintings in the future, which either could argue fits within their historical art narrative.
Fate of Germany's 'degenerate art' revealed
Hitler considered modern art movements such as the Surrealists, the Expressionists and the Dadaists should be grouped under the term "degenerate art".
Chagall, Man Ray, Picasso and Matisse were among the artists he targeted - the latter two for their interest in non-European, primitive art, which he deemed a "crime against German culture".
Cultural diplomacy in the Turbine Hall?
This morning, the culture secretary Maria Miller announces that Tate Modern has entered an 11-year deal with the Hyundai motor company to sponsor its ongoing series of Turbine Hall commissions.
The aircraft hangar-like space has been home to some of the most popular art installations of this century - from Doris Salcedo's Shibboleth, which opened up a fearsome fissure in the floor, to Ai Weiwei's audacious scheme to fill the hall with millions of porcelain seeds (a work the gallery subsequently bought).
Tate Modern announces new Turbine Hall sponsor
It is highly unusual for a company to sign up to an 11-year sponsorship. The norm is a three-year deal, sometimes it can be five, but 11 is extraordinary. And very risky.
In my experience, most corporate sponsorships involving consumer brands with physical products to sell fail to live up to the sponsor's expectations. Typically, the company doesn't achieve the shift in perception it had hoped for, nor the consumer recognition of its involvement in the arts.
