Arizona Kid

Arizona Kid on Ebay
Arizona Kid comic book #1-6, March 1951 - January 1952.

Was this an original Marvel/Atlas character, or did he originate elsewhere? Roy Rogers starred in a film called The Arizona Kid in 1939, but that was too early for this to have been an adaptation.

Another character under this name also appeared in the Dell series The Comics in 1937-38, who might have been in a newspaper comic strip first.
