A rare artwork by pseudonymous street artist Banksy is on sale at a Stratford gallery - and it could be hanging on your wall for a mere £50,000!

Lambert Fine Art, in Bell Court, has taken possession of Grannies, one of only a couple of examples of his work that come onto the open market each year.

Published by Pictures On Walls, the framed 57.5x76.5cm limited-edition print from 2006, was obtained by the gallery through a mysterious ‘private source’ linked to the artist and comes complete with a certificate of authentication.

Rendered in Banksy’s signature black and white stencil style, the pair of grannies are set against a block pink background, serving to heighten the humorous contradiction between scene and message, a technique mastered by the artist.

Director Mark Lambert said: "We are so excited to bring to the market this wonderful piece. I have personally sold many prints by Banksy over the years including an original spray work on canvas which in today’s market would be worth millions.

“This Banksy titled ‘Grannies’ is truly exceptional and in perfect condition. It’s framed and glazed with museum quality glass to protect the work for the future.”

“We are also very lucky to be working with the neo-psychedelic-cosmic-abstract-expressionist street artist Sickboy who personally worked with Banksy on many of his shows including The Bristol Museum exhibition and Dismaland in Weston-Super-Mare.”

Active since the 1990s, Banksy’s works of political and social commentary have appeared on streets, walls and bridges throughout the world but the identity of the England-based artist remains unknown.
