In 1980 Kenner Canada put their ESB overstock figures in these open window boxes and distributed them via Sears. The reverse of the box shows all 5 action figure set, as well as the Turret & Probot playset and a Tauntaun.
4 sets included a shrinkwrapped cardback, see the figure to the right from the front. Obi Wan was on a regular cardback, as he was never available as a shrinkwrapped figure.
