There are some pics, but they've never seem to make it up online. He looked bad in them, you wouldn't be able to tell the difference between him and your average bulky man. The few candid ones I've seen show him smoking, pretty fat, and eating doughnuts by the box full. He also had a fondness for Zubaz or sweat pants which added to the look. The one saving grace was that his face stayed leanish through those years.
Losing the Olympia did a number on him, coupled with heavy amphetamine use. There are stories of him running around naked, hiding thinking Arnold was sending hitmen after him, etc.... Real speed freak stuff.
