I can see where Lyons may have been hesitant to just lump this in with Dell COMICS... because it's not a comic book. Dell published a lot of things besides comics. You can't actually tell that from just looking at the cover, though, and just tossing it in with the rest of the Dell comics might lead to disappointment by some when they discovered it was a children's book rather than one of their movie comics. "Odds and Ends" does seem like the appropriate category in this case. Come to think of it, there were several publishers (Avon pops immediately to mind) who did things like adapting novels that they had the rights to, into comic books. "An Earth Man on Venus" would be a great example. I'd love to see someone post a scan of the paperback novel; it would make a great companion piece to the comic.
