Polish duo Sainer and Bezt, collectively known as Etam Cru, paint massive-scale murals of people and animals on blank building faces around the world. Their unexpected visuals liven up dreary urban surfaces, often stretching dozens of feet into the air. Some of the tallest, in fact, cover ten-story facades.

Recent collaborative works include a blue-haired girl bathing in a jar of strawberry jam entitled ‘Moonshine’, painted as part of the Richmond Mural Project in Virginia, and ‘Madamme Chicken’ in their native Lodz, Poland.

Each painter also works solo, as well. Sainer’s work is reminiscent of graphic novels, while Bezt works in brighter colors and a somewhat more realistic style. Check out more at their blog and on Facebook.
