Rare screenwriters conference ad 1980

Here's an interesting little cutting that was kindly sent to me by our friend in the States, Kevin Walsh. It is from the Screenwriters Conference 1980 and took place at the Sherwood Oaks Experimental College. What is interesting about this event is that it featured two writers that had just worked on Clint's (then) latest movies. Richard Tuggle had worked on Escape from Alcatraz in 1979 and Dennis Hackin who had worked on Bronco Billy in 1980.
