Overstreet identifies this painting to be the work of Harold Winfield Scott who painted covers for pulp magazines, and Gary Watson specifies the source of the cover as the October 1947 issue of Trojan's Speed Western Stories.
The cover is pictured in The Frazetta Treasury (1975) where it is identified as Frank Frazetta's first published oil painting. However in the early 2000's, Frazetta said it was not his.
