Downtown Vegas used to have an area affectionately referred to as The Boroughs, right on the cusp of 18B. At one point, there was more art there than you could fit into your range of vision. It was impossible to turn around and not see more painted walls.
This one was to the right of a bunch of signatures, and next to the gateway that led in between the buildings. Every inch of the building, and everything it was attached to, had been covered multiple times by different murals. This was probably the most intricate.
