The Andipa Gallery, at Knightsbridge in London, is recently held a selling exhibition of rare works by the UKs leading urban artist, Banksy, including the largest canvas ever to come on the market.

All of the works on display were from the galleries collection, built up over the last three years.

The largest canvas for sale is “Are You Using That Chair”, a signed oil on canvas measuring 213 x 426 cm (84 x 167 ¾ in.)

The exhibition, which was not an official Banksy show, ran until Saturday 16th May.

For those who are unaware of the work of Banksy, Banksy is an unknown artist who started by painting street graffiti in the UK, and became known as the “urban guerilla artist”. He now has international acclaim and his studio works fetch very high prices.

Unfortunately the prices of the works in this exhibition were not displayed in the catalogue or on the web but were shown as £POA (Price On Application)
