Old marketing posters from late 80's

A friend of mine returned to me some old Heurikon posters I had given him a long time ago, for my birthday recently.
Apparently, he had them all these years from when I worked there from 1987-1990, saved them, and just gave them to me now.
They can be seen here: http://www.briandonahoe.com/PhotoAlbum/Heurikon/index.html
Back in the day when Heurikon was big on real actors, elaborate setups, and super-heros; for their marketing.
