Swedish comic artist Joakim Gunnarsson recently bought two folders with scripts and plot ideas by Carl Barks and today Joakim posted that he found script pages from late 1961 or early 1962 for an unfinished Uncle Scrooge story. The title of the story is Happi Happi Island and on his blog Joakim describes the nine-and-a-half script pages of what would possibly have been a 20-page story.
This is very exciting. It would be great if this material was published somewhere once, or even better: completed and drawn by someone like Daan Jippes. And who knows what other material is still out there!
