Gusto GSB BTM is a legendary graffiti writer from San Francisco. Some people say more and do less, but GUSTO is exactly the opposite. I would label Gusto as a hardcore bomber and graffiti enthusiast who gets up more than just about any writer. His tags and iconic GU throw-up are everywhere and anywhere real graffiti is. With decades in the game and no sign of stopping, pay your respects to the legend that is Gusto.
