New Clear Era is part of a large ongoing project investigating classicism and legibility.
The regular version is the base font. Numerous permutations will be performed on this underlying skeleton. Also investigated are the ideas of an extended type family, and trying to understand what makes a contemporary legible, serif typeface.
The Mix versions combine characters from the Roman and Display to make quirky fonts that can be comfortably used for setting text. Mix One is the most quirky; Mix Three is the least.
