When we last updated you on Spanish street artist Sam3, he had just completed a set of three sweet murals in Madrid. We now have images of another great piece (his newest) also featuring his signature shadow technique, this time in Poznań, Poland, painted for the Outer Spaces Festival. Entitled Power to the People, this newest wall is dedicated to the Spanish Revolution and the current May 15th movement.

More pics after the jump…
