Klub7 - a group now based in Berlin - did this work last Summer in their hometown Halle/Saale for
All you can paint Festival

The second collaborative mural i like to show is by
CHU, TEC & P3DRO from Buenos Aires in Barracas - Buenos Aires/ Argentina during Meeting of Styles 2012.
It's kind of funny to see two works that have a distance to each other of at least 11500km done in same color scheme. I like both ;)
