El Muro (The Wall)
"(El Muro) is a tour de force: it is a still life featuring a solid expanse of old, peeling, blotched, cracked plaster wall. If ever there was a subject for the modern cults of decay and degradation, this was it. You would not believe that it could be made beautiful - beautiful and inspiring by the sheer perfection of workmanship; neither did I until I saw it."
- Ayn Rand
