I didn't know that Snap, Crackle and Pop had adversaries named Soggy, Mushy and Toughy!
To be a child sitting in a theater in 1939 and watching a commercial sponsored by the Kellogg Company.
It probably ran back to back with a Popeye cartoon, before the news reel, previews, and the main attraction. This is a piece of history from the golden age of advertising via the big screen.
I hope you enjoy it as much as I have!
