A SHOPPING centre 3D masterpiece that depicts the world’s most iconic painting has been completed.

The stunning painting, based in the Brunel Shopping Centre is the product of five days hard graft by world-renowned pavement painter Julian Beever, who specialises in creating mind-boggling 3D optical illusions.

This week the artwork left hoardes of visitors pondering whether an underground vault had opened up in the floor to house the Leonardo Da Vinci’s classic painting.

Julian’s expert techniques give the illusion that a chamber has opened up in the new floor, with a painter perched precariously on the wall as he makes the finishing touches to Van Gogh’s work. The painting has a twist with Mona Lisa in turn painting the artist, to reflect this year’s theme of art.

“This is art within art within art. This is probably the most famous artwork in the world and something that everyone can relate to. When I heard the theme was art I was instantly drawn to creating this,” Julian said.

The artwork forms part of the Brunel centre’s summer festival StreetFest 2015 featuring musicians, dance performances, craft workshops and a graffiti wall.

Using only multi-coloured chalk and a grid the Julian has painstakingly recreated Da Vinci’s iconic work which will remain on display indefinitely in the Brunel centre During his 30 year career, Julian’s chalk drawings have drawn critical acclaim with his work popping up on streets from America to Asia.

The free Streetfest 2015 event gets underway on August 28 from 11am and will run daily from 11am to 3.30pm.
