Who Made These Dennis Richmond Portraits?

This scene is kind of old news at this point (Junk Thief covered it last week), but TK really likes these portraits and wants to know who the artist is. Somebody want to take credit?

In any case, this display is nice and all, but not as cool as when that band played a free happy-hour rock concert on that same overhang.

Update: Wow, yeah, this portrait takes the cake. Thanks, Troy!
