Indicia title is "JACE PEARSON OF THE TEXAS RANGERS, No. 648." Code number is J.P.O.S. #648-559. Copyright 1955 by Stacy Keach. This Four Color issue comes after "Jace Pearson of the Texas Rangers" (Dell, 1953 series) #9 (February-April 1955) and before "Jace Pearson's Tales of the Texas Rangers" (Dell, 1955 series) #11 (November 1955-February 1956), so it was apparently intended to be #10 of one of the series. Based on the 1950-52 NBC "Tales of the Texas Rangers" radio series.
Story continues on inside back cover in black and white and concludes on the back cover in color. The last panel is Dell's "A Pledge to Parents."
