Who's That Guy? - "Hollywood Steps Out"

Cartoons from the 30s and 40s often contain caricatures of celebrities of those times. While some of the caricatured stars are easily recognizable still today, other may look rather obscure.
The series of posts that I start today will help you identify all the caricatured people from various cartoons.
