El viajero que vino del infinito

A Spanish pulp science fiction cover depicting a figure in a conical helmet and cape—armed with a ray gun—alongside two startled earthlings. Published by Bruguera in their Futuro imprint, this booklet exemplifies the pocket-sized adventure magazines that flourished across Europe in the mid-twentieth century. Lurid painted covers sold stories of interplanetary conquest and alien contact to working-class readers hungry for imagination beyond daily life. The genre vocabulary—the flash of technology, the implicit threat and wonder of the unknown visitor—became foundational to comic book visual language and the science fiction narrative conventions that followed.
