How did graffiti morph into Street Art and become a global art market worth millions of pounds? Our Blue Badge Guide Rachel Kolsky will be joined by Joy Frith for this exploration of London’s Street Art scene, introducing you to the best of Street Art and the stories behind the artists too. From murals linked to peace and urban regeneration to early iconic pieces, many now vanished forever, to current day hubs and a collaboration with the Dulwich Art Gallery, it is clear that London is truly an open air art gallery, open 24 hours a day throughout the year.
