One of the joys of doing things like Reading Room...
...is uncovering a long-lost treasure, like this never-reprinted tale from Atlas' Journey into Mystery #50 (1959)!
With a (admittedly somewhat-misleading) cover by Joe Sinnott, art by Steve Ditko, and script probably by Larry Lieber (Stan Lee almost always had his byline on his own scripts), it's a great example of the sort of energy and creativity that was just waiting for a spark to coalesce into what would become Marvel Comics only a year or so later.
