1964 Jonny Quest S01E20 The Invisible Monster

I was born in 1964 so, I did not see the original broadcast of Jonny Quest but, I did catch the re-broadcasts, Saturday Mornings, in the 1970s...what a great time to be a Kid. Jonny Quest was and is one of my all time favorites...Here is
a cartoon from those great days:
The Quest family and their bodyguard investigate strange phenomena and battle villains around the world.
