Boys' and Girls' March of Comics #116

In "Roy Rogers King of the Cowboys at Rustlers' Gap!", Roy Rogers races to save the Brannan boys after a frantic message from Pat sends Bullet galloping through the canyon. With Nellybelle stuck in the mud and the boys trapped in rising waters, Roy, Trigger, and Bullet use clever traps and teamwork—snowballs and a cleverly placed rope—to outwit the rustlers and reclaim the herd. Written by Gaylord Du Bois and illustrated in the classic Western style of the era, this action-packed adventure captures the spirit of the frontier with a touch of whimsy.
