On the show today, Allen McKellar told us about his adventures as an African-American salesman of Pepsi in the Jim Crow South.
Images from that era on display now at the Queens Museum of Art and in Stephanie Capparell's book The Real Pepsi Challenge.
It's sobering to think that showing black families in advertising could have been quite so pioneering. (Listener challenge: Spot the future U.S. Secretary of Commerce.)
Thanks to Laura Silver for putting this slideshow together.
