To stop a group of outlaws hitting frontier settlements, a disguised Sheriff Solar joins a supply caravan and is captured by the criminals...
Buy, if there was ever proof that "space opera" was just "horse opera" with ray guns instead of six-shooters, this was it!
Veteran pulp and comics writer Walter Gibson (The Shadow) also wrote the space western series Spurs Jackson and His Space Vigilantes.
Artist E.C. Stoner (Blue Beetle) had a long career in both pulps and comics from the 1930s to the early 1960s.
Though he had illustrated both Doc Savage and Ajax the Sun Man for Street & Smith (which also published The Shadow), he didn't work with Walter Gibson until they teamed up on Blackstone the Magician for Vital Publications.
(Gibson was a close friend of Harry Blackstone, as well as being a a tlented amateur magician, and wrote all the comic stories based on the celebrity magician at the various publishers who licensed his character as well as scripts for the radio show and "how to do magic" books under Blackstone's name.)
Even after Blackstone moved to Atlas (later Marvel) Comics, and other artists took over, Gibson and Stoner worked on other projects including these promo booklets for Vital.
