This is a Jose Clemente Orozco's frescoe. It represents Miguel Hidalgo, considered the father of the Mexican independence.
This mural is inside the Government Palace in Guadalajara and it is breathtaking. I managed to capture a small part of it and I was basically liying on the floor, not ROFLMAO ;) On your right, you can see one side of the double staircase in which the mural was painted.
This is a great shot. Getting the stairs in really help put the size into perspective. The colors of this are amazing. I would love to see this in person.
