Pablo Guzmanis a Columbia-based painter whose work is well known for pushing the boundary between subject and viewer. His series “Homenaje al cuadro”, is basically a succession of paintings of people with their backs to the viewer. It seems that each of his subjects are looking at something infinitely interesting in front of them. It kinda makes you want to shove them away to find out what they’re looking at.
