It was Humphrey Bogart. And it wasn't Gerber. According to Snopes.com, it was Mellin's baby food
that had him on the label, thanks to Bogart having a mother that was a commercial artist.
FWIW, Bogart was 30 when Gerber started selling baby food.
I liked Seymour in the original Battlestar Galactica.
Thanks for the info.
