Over the recent "Snow-pocalypse" I've had a chance to look at some of the logos from the MLB (Major League Baseball).
I found the evolution of certain logos to be interesting. It was subtle changes in the Dodger's logo that fascinated me being one of the oldest teams in baseball. To be honest, I am not baseball fan. But, I discovered that studying the teams/logos of this particular league was in my best interest. The history behind the choices made in designing these uniforms, logos, and merchandize give me a wider perspective of how/what I choose in designing my own.
