Black Lightning Used to Be a Western Star

"Black Lightning Used to Be a Western Star" from All-American Western #103 (DC, 1948) by Robert Kanigher and Alex Toth

Picking up the numbering from All-American Comics after interest in superheroes evaporated in the late 40s, the book became the home of western stars like Johnny Thunder, before turning into All-American Men of War after 24 issues and for the remainder of its existence. It probably helps that Thunder was named after a JSA member, because All-American's other features aren't so well remembered - Overland Coach, Minstrel Maverick, and Foley of the Fighting 5th.
