Hanna-Barbera Scooby-Doo...Mystery Comics #28

Gold Key

Scooby and the gang are at the Museum of Ancient Art when an Egyptian sarcophagus begins to cough and smoke. The curator, Mr. Hadley, arrives to extinguish it, but it turns out to be a self-destructing tape recorder. Meanwhile, thieves have made off with an Axtakl artifact called the Ancient Astronaut. Clues point to the thieves returning with the artifact to Axtakl, so the museum offers to fly the gang down to Central America to retrieve it.
