A kind reader has commented with the real info regarding this lunchbox:
this lunchbox is from the TV series “Men Into Space” which aired from 1959-1960. The sci-fi series was actually pretty well done and featured William Lundigan as Air Force Col. Edward McCauley.
I admit I still like my made-up description, so I’m leaving it here at the bottom:
Representing the Air Force in space, Colonel Ed McCauley has a smart red ray pistol and a determined gaze. This dashing young redhead enjoys free-fall, tethered space walks, and defending Earth from outside forces.
