As a kid in from the '60s, I remember watching and being amazed at Mr. Magoo. He was human, when most of my cartoons were animorphic characters or super-heroes. And he was flawed. He was an elderly near-sighted fiesty guy that would often get into trouble because he couldn't see well. But this series didn't focus on that or on the humor. From September 1964 to April 1965, he was the star of a series called "The Famous Adventures of Mr. Magoo". It was 26 episodes, each cartoon telling a famous piece of literature and featured Mr. Magoo as one of the "actors" as if it were a play. And at the beginning of EACH episode, Mr. Magoo would do a little funny intro featuring an aspect of the story in his unique and funny way. And I have taken a HUGE leap of faith in saying this storyboard was created by Bob McKimson because he was the Animation Director for the series. I couldn't find a specific resource identifying the actual person, but McKimson had to be heavily involved in some way.
This storyboard is 1 of 3 for the introduction to the Noah's Ark feature. This particular story was the 23rd episode.
Attached in the "Additional Images" section below is a page showing screenshots of the cartoon. This way you can (if you wish) see how the storyboard converted into the cartoon.
