I took pictures of the various panels of the mural. Notice the rich colors of the mural, as well as the subjects depicted in the mural.
This particular panel is my favorite. Here, you have a Communist soldier, kneeling with his gun ready to fight. Siqueiros was a member of the Communist party in Mexico. Consequently, his works had very high charged political overtones to them and in some cases, his works were so controversial, they were whitewashed such as what happened to "La America Tropical".
Of all of the 3 BIG Mexican muralists, Jose Clemente Orozco, Diego Rivera, and David Alfaro Siqueiros, Siqueiros is by far, my favorite. I LOVE the passion that can be seen in his work! His work just seems to come alive! To view more information and see the entire mural, go to: http://www.sbmuseart.org/siqueiros/mural_imagery.html.
