Art lovers and the people concerned for the famous gallery in New York got a shock. An artist secretly hung his art work in the Metropolitan Museum of Art, Brooklyn gallery, Natural history museum, and the Museum of Modern Art. The name of this artist is Banksy. He wants to be called not an artist but a quality vandal. Another surprising fact is that staff members did not distinguish between a great work and Banksy's funny work for a while. Banksy wanted people to question what the standard is between funny work and masterpiece. Banksy succeeded in fooling the art lovers and staff members of the gallery in New York.
