Beadle's Half Dime Library No. 1074

"Mustang Merle's Mandale," by Major Sam S. Scott, depicts a man with lasso and revolver fending off dive-bombing eagles while mounted beside a saddled horse in arid terrain. The cover announces adventure pulp's stock elements: the West, exotic wildlife, and a capable protagonist in extreme circumstances. Published weekly at five cents by Beadle and Adams, the Half Dime Library pioneered the mass-market adventure serial format that preceded pulp magazines and comic books. Wood-engraved covers like this sold narrative excitement to working-class readers through action imagery and melodramatic typography—establishing visual conventions that would define adventure comics for decades.
