Maybe a mural, part 18

Here's another wall. It's different than the previous "maybe a mural" posts, part 16 and part 17, because the wall is better covered with decoration. But then, what about that uncovered patch at the left side?

The wall is at 2601 N Tucson, the west side of the street, at the corner with Copper. (I rode by on November 25, 2010.)
