Poop in the air, poop in the trees, poop on your chin, poop on your knee: Mexican artist Carlos Amorales' children's book revels in the stuff, rendering these scenes in bold, scatological brown and black silhouette. Amorales (born 1970) has already established an impressive reputation as an artist working in a variety of media--animation, performance, video, sculpture, photography and works on paper--and here explores that singular niche within artists' publications: the artist's book "sort of" for children and definitely for adults. "Caca Grande" plays fast and loose with the brown stuff, dispatching it to places it had previously never been, with joyous abandon.
