"The symbol became so synonymous with the film that it was possible to remove the actual text of the title in certain instances." Saul Bass, A Life in Film & Design Jennifer Bass & Pat Kirkham This clipping from the Los Angeles Times amply makes the point. It gives too a sense of what typical newspaper film advertisements looked like then and how much Bass's work challenged those conventions.
This post, as well as the two following, show some Anatomy of a Murder material you won't find in the Bass biography. But then it would have been considerably more than 424 pages to include everything that came out of his studio. Get this book!
