Twin Earths

From 1950 onward, New Century Press’s Twin Earths spanned 29 issues, a long-running science-fiction comic primarily written by Oskar Lebeck and illustrated by Alden McWilliams. The series explored the premise of a hidden, advanced sister planet to Earth, blending Cold War-era anxieties with imaginative cosmic adventure. Its sustained run and consistent creative team made it a distinctive, if lesser-known, fixture of mid-century comics.
