Fighting fire with fire works, so why not fight graffiti with ... graffiti?

Prague's public transportation used to be constantly at war with graffiti artists defacing its tunnels. Painting over the graffiti never worked as a permanent solution, until authorities gave several local graffiti artists their own wall to paint on. The artists spray-painted beautifully massive murals to help curb illegal graffiti in the tunnel.

Prague Public Transport plans to expand the success of its graffiti project before the end of the year by implementing it in other train stations across the city.
