Starlog Press published a magazine specifically devoted to Star Trek II: The Wrath of Khan. I believe it was first available around the time of the movie's release in June 1982.
I sent off an order form for this magazine on 19 July 1983, and it finally arrived on 4 October of that year. I have several impatient exclamations in my diary through the months of August and September lamenting the slowness of its arrival!
Here's a great shot of Kirstie Alley's Saavik. I loved the Saavik character in the second film, and far prefer Alley's performance to that of Robin Curtis in films three and four.
A few storyboards from the film.
