There are quite some interesting works in Katowice from last year's festival, and works outside the frames of the festival. Here is what I found:
A great wall by Aryz in 2011, next to the murals by Roa, Moneyless, Tellas and Ganzeer.
Easy and effective - total makeover
A well placed Madonna in front of the church
These prehistoric fishes are several places:
Weird alien in an underpass
Translation something like: Katowice needs a hero!
City without graffiti is a city without soul!
Work by AM
Translation would be something like: The one black sheep - or direct translation: The one bad chicken of the mother
A great mural by Elsner in Mariacka alley
