Morales, a Mexican painter, passed away in 2001 at the age of 75. He was best known for his paintings of rural Mexico with an almost surrealist bent. More often he has the "magic realism" tag hung on him--that isn't a bad thing really. Any attempt to force an artist into a box, however, does them a disservice. You don't need a school or a genre. We can all see the work.
Friedeberg's surrealist pieces use geometry and religious symbols. He also created the famous "hand chair" sculpture you may have seen and other sculptures in a surrealist vein. He was born in Italy but escaped soon to be war-ravaged Europe at the age of 3 and was raised in Mexico. His still irreverent work adheres to the surrealist ideology.
