This was a Hanna-Barbera Cartoon that ran from 1966 - 1968 on CBS. It premiered on September 10, 1966. They are approximately 8 minute long cartoons that sandwiched another cartoon called Dinoboy In The Lost Valley. These same cartoons were later paired with Frankenstein Jr. in The Space Ghost/Frankenstein Jr. Show in 1976. Space Ghost was an outer space crime fighter who had the ability to turn invisible and had a pair of wrist bands that projected force fields and various rays. He was accompanied by the twins Jan and Jace and their monkey Blip. Jan and Jace usually got in trouble and Blip would get everyone, including Space Ghost, out of it. But when push came to shove it was Space Ghost's powers that came through.
