Pbs Treasures of the World: Guernica Testimony of War

A wonderful site describing Pablo Picasso's "Guernica," a mural he created for the 1937 World's Fair. The resource examines the civil war raging in Picasso's homeland of Spain and the frustration he felt toward the violence taking place there. Be sure to check out the "Education," link on the left side. It has a lesson plan that goes along with this artwork.
