I liked this article because it gives you a real window into Doug’s hectic daily life circa 1980. A lot of articles at this time tend to rehash a lot of the same bullet historical points. But, this one mixes things up, and even throws in an anecdote about Doug’s abandoned shark illusion. 

Doug’s old Van Nuys HQ still exists by the way. I took pictures of it a few years back that can be found: HERE.
