Joe Cox is another post office muralist about whom the web knows little. From what I can tell, his work tends to have a strong graphic design element. Many of his industrial-scapes would seem abstract if they weren’t. Weird, eh? A little sketchy. Not surprisingly, his work did evolve (I’m guessing) to the abstract. Personally, I love his painting titled Yellow Wall.
Cox made at least one post office mural: Clearing the Right of Way (Garrett, Indiana).
