Betz & Sainer are two Polish artists (from Łódź and Turek, respectively) who collaborate under the ETAM Cru moniker and are just as comfortable creating screen prints and canvases as they are painting huge-ass murals. The attached images are just a small sampling of their work so, if you want to see more, hit up their individual blogs (Betz / Sainer) or the official ETAM site. Enjoy!
P.S. If you like what you see here, be sure to check out Aryz’s work, too.
