I've seen many hundreds of photos of him, and I'm afraid he wasn't generally this well turned out. Oh, he wasn't a slob...he just wasn't a Gore Vidal or William Saroyan.
And yes, he was just that fucked up, if not more. My master's thesis (which I may expand into a book) plus an article I have coming out soon were on just this. If anyone's really interested in how screwed up he was, read Tom: the Real Tenessee WIlliams by Lyle Leverich, or Cry of the Heart by Dotson Rader. Fascinating stuff. Considering how insane the rest of his family was, he actually was (in the immortal words of Frasier Crane describing Cliff Claven in light of Cliff's mother) "heroically well-adjusted."
