Shepard Fairey (OBEY) and Vhils collaborated on this street art/mural in Lisbon, Portugal. Both are iconic artists in the street art scene worldwide. Some collaborations are forced, but these two - both hugely collectible in the urban art/graffiti/street art scene - just always work. An amazing piece to see in the flesh. The vibrant colors and bold designs of Fairey and the texture of chiseled plaster by Vhils flows well.
