If you have not seen these, take some time and hit play. Save some time skipping the same opening sequence over and over. Each episode is about 6-7 minutes. Although listen to the opening sequence at least once. My favorite of all the TV/Serial Live action or animated before 1990.
"THE JEWELS" So basically most of the episodes feature Mad Scientists committing robberies and destruction. A few harken the WW2 times with German and Japanese stories. My favorite may be Episode 5 with a giant dinosaur. A 1990s Superman episode pays tribute when Luthor brings a Museum T-REX robot to life. But this episode is pre-Godzilla.
TRIVIA - Episode One was nominated for BEST ANIMATED SHORT Oscar. Lost to Disney's Pluto, but I challenge you to find better work of the time...
