On the first issue of Dell's I Dream of Jeannie (Apr/66), the artist takes that to the limit.
On this page, the Tony Nelson faces in panels 1 and 4 are identical. Likewise his faces in panels 2, 3, and 6. (After panel 2, that one is flipped left for right.) In places the head is the wrong size for the body; in panels 1and 5 it's also turned far away from where he should be looking. It's not in the same artistic style as scientist Stella's face at all.
These are the main two images of the character face the artist uses throughout the comic, over and over, traced originally from photos of Larry Hagman. I see a couple of different stats used sparingly on other pages. He relies on only one or two of Barbara Eden as Jeannie, although on this page it looks as if he's actually drawn her face. In a few spots he draws Tony's face—a very few.
"Sky High" is a full-length three-chapter story. The writer is Paul S. Newman, but I have no idea as to the shortcut-taking artist. (For what it's worth, the Grand Comics Database attributes the art to someone the Who's Who never heard of, a Michael Arnes. My level of confidence in the ID wouldn't be improved by finding it a misspelling.)
