A few weeks ago the UNICATS Graffiti Jam went down in Warsaw (Poland). On two days local and international Graffiti Artists gathered together for some really nice wall productions. We just received the photos of the Event and the final walls with Graffiti Artists like Riam, Nomad, Hombre, Anus aka Paco, Opium, Zeus, Nokor, Roice and many more! Check it out after the jump! The Event was supported by MOLOTOW!
