Snub's signature large-scale robot characterisations

Short Fuse, Ben Oakley Gallery

ART: Snub is a graphic street artist who came to prominence in the 1990s, inspired by fictional robot Hammerstein.

His high impact graphics are used to make a statement on anything from feature films, album covers, clothes and toys, but his most striking impressions are made when his robots take over an entire building facade.

Snub works on a range of media including brick, metal, glass and card and uses graphite, stencils and freehand spray paints.

Street art has become more mainstream, moving from alleyways to art galleries and the Ben Oakley Gallery in Turnpin Lane, Greenwich, is presenting new works by Snub in his first solo London show, called Short Fuse.
