I got absolutely amazed by this picture. It looks like the lion is consciously performing for the camera, posing. And the characters expression is as it was a regular scenario to shoot a lion roaring right in front of you.
When someone looks at a company’s logo evolution, usually there are several variations through the years (like with the 3M logo). With MGM, we see the exact same lion roaring since 1957.
The evolution of the lion is shown in retronaut.co.
