I am in the process of plugging some gaps in the Typographic Timeline in my overall collection, and I noticed that—given the impact on my personal life—the late sixties and early seventies are grossly underrepresented.

Does anyone have any suggestions on typefaces particularly evocative of that era? There are a number of typefaces in the PLINC library which are original or derivative, but House Industries hasn’t gotten around to doing whatever they have to do to the source material before the letterforms can be used for their online headline service. But, I don’t to step on any toes, so other sources would be appreciated.
