Shores is credited on both pencils and ink on Wild Bill Pecos by Jerry Bails' Who's Who, and artwork similar to his credited stories in Black Rider, with horses, and some hats with very curled-up brims in front view, and also the round dents in the hat looking like two spooky eyes.
Notes as for the other Syd Shores story.
Penciller credit from the French fan magazine Back Up #14, as submitted by Stephane Petit, via the GCD Errors list, February 2009.
Buscema is credited on both pencils and ink on Nuggets Nugent by Jerry Bails' Who's Who, and that this is Buscema can be confirmed by the hats with two thin arched lines in front, and a sideview with very high upturned brim, which can be found in his many Roy Rogers stories.
Rosenberger is credited on pencils and ink for Orbit Publications by Jerry Bails' Who's Who. He can be recognised by his distinct faces with rather small features, and "soft" movement with actors wondering what is going on. He is best known for his many stories in "Adventures of the Fly" and "Adventures of the Jaguar" for Archie.
