Tristan Eaton, Kid Acne and Calma spent this past Tuesday @ Plastik in Sao Paulo as part of the Brothers in Arms tour. The trio dropped their skills on the outside of the toy boutique and also hit a wall inside. After that they held a signing at the store. Lucas Penido caught the painting action for The Hype BR blog. Check out a few more pics after the jump and hit up Lucas’s full posts for more (store front, store front 2, inner wall).
