Though Buster Crabbe starred in more Westerns than any other genre...
...he's best-known to the public at large as the movie serial heroes Flash Gordon and Buck Rogers!
Here's a tale from his own comic that combines both Western and space hero concepts!
Note that Buster is actor Buster Crabbe, not "Buster Crabbe as a character like Billy West" or somesuch in the tale, and it's assumed that he's actually able to do anything he's shown doing in his films.
The amazing art for this tale from Eastern Color's Buster Crabbe Comics #5 (1952) was by Al Williamson, Roy Krenkel, and Frank Frazetta, who were astounding comics fans with similar quality work at EC Comics on Weird Science and Weird Fantasy!
The cover was by Frazetta, who was also doing covers featuring Buck Rogers (whom Buster had played in the movies) for Famous Funnies, as well as illustrating the White Indian strip and covers for Ghost Rider! so he had handled both sci-fi and Western genres before doing this mixed-genre piece!
