That's right, when this thing came out in 1982 the term 'Graphic Novel' wasn't as commonly used as it is today. But that's basically what it is. A movie adaptation graphic novel, no less!
Oh, and do you see, up at the top right of the back cover: 'Illustrated Fiction.'
And at $6.95, this was a pretty pricey...ahem...comic book...in 1982!
