Here's the first six-comic volume in the complete series of Mysterious Adventures, a raft of freaky fables including this cautionary yarn when adventurer David Murstone crashes in the jungle and is severely injured. Jivaro goddess Konocry saves his life by letting him drink from the "Pool of Eternity" and thus giving him immortality. The Jivaro tribe disagrees with her action and tortures the couple. Since they cannot die, they have to endure eternity as shrunken heads. Collects issues #1-6 (March 1951 to February 1952).
