Here's a tale that could've inspired the movie They Live! as well as several Twilight Zone eps...
...plus it has a rather unique aspect we'll explain at the conclusion...
"We take our leave of Herman Scudder, who discovered that "reading" people can be as easy as reading an eye-chart...in the Twilight Zone..."
(Sorry, instinctively channeled Rod Serling for a moment...)
Pencils and inks for this never-reprinted story from Harvey's Black Cat Mystic #57 (1956) are by Jack Kirby, who rarely inked his own work since editors felt his time was better-spent penciling at a rate of up to four pages per day!
(Yes, I said per day!)
Probably written by either Kirby himself ,or partner Joe Simon.
