The Further Adventures of Indiana Jones #18

In "The City of Yesterday's Forever!", Indiana Jones and Marion arrive in the mysterious city of Ra-Lundi, where they're thrust into a deadly ritual involving sasquatch-like beings. With help from a shadowy figure known only as the Man in the Mask—whose ties to the enigmatic Abner remain unclear—they barely escape before the city itself is destroyed. Back at the National Museum, Indy and Marion face a new blow when Marcus reveals the Arnhem Ring is a fake and he’s being replaced as curator. Written by David Michelinie and illustrated by Herb Trimpe, with cover art by Trimpe and Jack Abel, this 1984 Marvel adventure blends ancient secrets with high-stakes peril.
