Banksy : King of urban art

Banksy's stencil piece "Paparazzi Rat" is one of his most iconic works. Starting April 15, 2016, collector Dirk Kronsbein is showing 45 works from his Banksy collection, many of them originals, in his Munich gallery. Kronsbein has said he holds Banksy in high regard due to his social activism.

Banksy is not only critical of society, he also has a sense of humor. Here, he's depicted the Queen as a chimpanzee in royal regalia. Banksy donates the proceeds from his works to charity. He was once able to present a six-figure check to a youth sports club after the sale of one painting. Dirk Kronsbein also plans to support sport programs for children with his exhibition.

Dirk Kronsbein only sells a Banksy work if he owns more than one copy of it - as in the case of "Choose Your Weapon." It's an homage to artist Keith Haring with his dog. Kronsbein also sells Banksy paraphernalia and donates the proceeds to boxing programs for troubled youth.

Banksy often deals with armed violence and armament in his work. In "Heavy Weapon," he shows an elephant with a missile on its back. While graffiti in urban spaces is often illegal, on paper they're collector items. Even copies can cost as much as 100,000 euros.

Not all of Banksy's works are political. He's also created poetic stencil paintings like "Girl Nola," whose umbrella is spilling red and yellow rain. Who is Banksy? He remains an enigma and fiercely guards the secret of his identity. All efforts to find out who he really is have been in vain.

Owning a Banksy is a status symbol enjoyed by many celebrities. Actors Leonardo DiCaprio, Brad Pitt and Angelina Jolie, as well as model Kate Moss, all possess works by the mysterious street artist. Moss not only collects Banksy's works, but also became one: She had herself portrayed by him in the Pop Art style of Andy Warhol's iconic Marilyn Monroe painting.

Coldplay singer Chris Martin purchased the original painting "Girl with Balloon" at an auction. Not only celebrities, but also other artists like Damien Hirst collect works by Banksy. Hirst was among the first to recognize the street artist's talent.
