Walking through the evolution of street and graffiti art, you’ll see work from the big guns like Banksy, Shepard Fairey, Space Invader, and Roa, along with all the latest emerging artists. Throw the rulebook out the window and give the National Gallery a miss for today. Walking around discussing the history, processes, and first-hand experience from this art form you’ll see the old, the new, and maybe even the sprayed right in front of you. General admission. Please arrive on time or the tour will leave without you. Sorry, but no refunds for latecomers. Wear comfortable walking shoes.
