An unauthorised exhibition of art by British graffiti artist Banksy will open in Germany on Wednesday, bringing together more than 100 pieces. The Mystery of Banksy exhibition comes soon after Banksy announced the auction in England of one of his pieces to <a href="https://www.thenationalnews.com/world/europe/banksy-s-superhero-nurse-painting-to-be-auctioned-for-nhs-charities-1.1180512">raise money for National Health Service charities</a> and completed a new work at Reading Prison, near London.<br/> The elusive contemporary artist, <a href="https://www.thenationalnews.com/arts-culture/art/who-is-banksy-the-top-theories-and-how-he-keeps-his-identity-a-secret-1.1049700">whose identity remains a secret</a>, creates works that ask provocative questions, often using public walls to make a statement. His subjects have included the British government, corporate power<a href="https://www.thenationalnews.com/arts-culture/art/banksy-in-palestine-a-look-at-the-street-artist-s-work-in-gaza-and-the-west-bank-1.1031618"> and the plight of Palestinians</a>. His work sells for millions and he has previously criticised the industry around art.<br/> At the same time, he is a master of publicity and knows when to co-operate with industry insiders. When an unauthorised exhibition comes along, it can be tricky to determine whether Banksy had a backstage hand in matters.<br/> Regardless, his work is loved and admired far beyond the few who get to see an original spray-painted on a wall. In England this month, a Banksy artwork that depicts a nurse as a superhero doll is being put up for auction to raise money for the UK's National Health Service. He was also confirmed as the artist behind a new work on a prison wall in Reading. <a href="http://www.themysteryofbanksy.de/">The exhibition at the German Museum in Munich</a> will be open until May 2. In includes original work, reproduction prints, sculptures and video installations. <strong>See images of Banksy’s art:</strong>
