These are 30+ original pre-production concept storyboards, in colour with all sorts of little bits of card and details stuck on. Amongst others, the ones above show the concept of the evil "Zod" and his superpowers. Obviously Zod didn't end up wearing a helmet like this, which shows how early in the production these were used. These storyboards were probably never seen outside the original collection. They came from the Danziger Collection, from Elstree Studios.
