Cover Layout

As the books are on the talks that the designers gave, and are more of a archive to that talk, I think the date on which the talk was given, instead of the name of the designer gives the books more of a series theme, also the date is individual to each designer each cover is different. However the people who are most likely to read the books are the members of the Typographic Circle, so they would know some of the dates on which well known designers gave their speech.
