One of the best production logos (yes, I am blogging about a production logo, reason #68 that I am a film nerd)is the MGM lion logo. Starting in 1924, when Samuel Goldwyn, Marcus Loew's Metro Studios, and Louis B. Mayer joined studio forces, MGM used several lions before settling on Leo in 1957. First came Slats, then Jackie, Coffee, Tanner, George and finally Leo, which is the lion you see on most MGM logos.
Ralph Helfer was Leo's trainer and cared very deeply for him. Ralph started a new way of training that didn't involve whips or chains, but was based on respect for the animal.

Greta Garbo and Leo. She looks thrilled to be at work today!
My alma mater, Loyola Marymount University, used to borrow Leo for their sporting events and chain him to a tree as thier mascot. He was rumored to spend the night in the dorm lobby after a late night game.
Anything to intimidate the visiting competators!
