Bass had great influence, particularly on American advertising as Bass is responsible for many well-known corporate logos of the '60s. For example: Girl Scouts of America, United Airlines, the ones featured above and many others.

I found this information compelling being that I am an advertising major and have recently began discussing logo design in some of my courses.
