I mentioned these old commercials created by Jay Ward Productions (Rocky and Bullwinkle, George of the Jungle) over on our sexy sister site Ad Jab, but I thought you folks would enjoy them as well. It wasn't unusual for cartoon characters from television to appear in ads for cereal back in the day: General Mills used Rocky and Bullwinkle in their ads (I know for certain they were in ads for Cheerios, I'm sure there were others), and Kellogg's and Hanna-Barbera had a partnership as well (here's some examples, also from Ad Jab).
