"Unusual Tales", a series presenting Steve Ditko's comics from 1957 to 1959 that are in the public domain.
Not quite sure what I think of this story, I guess if I was generous I'd say it's a dated product of its time.
Nice art by Ditko, though. Of interest to those looking for echoes of work a few years in the future, take a close look at the window in the background of the middle panel of page 2.
