New Adventures of Huckleberry Finn: Captain Calidore

Hanna Barbera animation art from "The New Adventures of Huckleberry Finn", a 1968 live action/animation series where Tom Sawyer, Huckleberry Finn and Becky Thatcher get chased into a cave by Injun Joe, and visit a number of different worlds (each one having a version of Injun Joe as the villain) while they try to find the way home to Hannibal, Missouri. If anyone has any Alex Toth model sheets from this series, please let me know. This is Captain Calidore, a "Captain Nemo" inspired villian (complete with a Nautilus look-alike submarine). He wants to melt the polar icecaps and ransom the world to keep him from flooding it. Inspiration for Global Warming? :-) From the episode "Menace in the Ice".
