Aliens, lethal snowflakes and a resistance movement, and a family separated by time travel could describe a sci-fi film. It's the setting of "El Eternauta," a serial comic published in Argentina during the late 1950s.
A fragment of the original comic as it was published in book form, is now available through Carnegie Mellon University's Latin American Comics Archive (LACA).
The archive is a curated, online exhibit of comic strips and comic books with the goal of enabling researchers to visualize and employ comic strips and comic books created in Latin America between the 1920s and the present for pedagogical purposes.
