The relationship between animated cartoons and breakfast cereal goes back to the 1930s. But it was the weekly TV cartoons shows of the 1960s that permanently cemented the connection between the two. Dan Goodsell, on his Sampler Of Things blog, has posted a bunch of rare General Mills cereal box package backs featuring Total Television’s Underdog, King Leonardo, Tennessee Tuxedo, the Go Go Gophers, Jay Ward’s Rocky & Bullwinkle, Hoppity Hooper and Hanna-Barbera’s Space Kidettes. Great fun, whether you grew up with this stuff or just seeing it for the first time.
