Four teenage street kids have a new hangout in the city near a wall — the lone survivor of a razed slum. One of the boys nicknames himself Grafity and the wall becomes his canvas to paint the city as he sees it. UK-based Ram Venkatesan, writer of Grafity's Wall, says the idea struck him at a talk on street art at the London Design Festival last year. "I wanted to tell a story about characters involved in street art. Later, at the Mumbai Comic Con, Anand (Radhakrishnan, illustrator) expressed desire to work on something set in Mumbai," he says. Venkatesan then collaborated with Radhakrishnan, letterer Aditya Bidikar, colourist Irma Kniivila, and crowdfunded publishing house Unbound.
