US, The paperback magazine covers

Issue #1 front cover
Project Projects explains this short-lived countercultural publication on the Design Envy blog:
Combining an underground press outlook and aesthetic with mass market distribution, US: A Paperback Magazine, was edited by Richard Goldstein and published by Bantam Books. US provided "all the news that's fit to eat" over a three-issue run from June 1969 through May 1970.
The Design Envy post also generously includes videos showing the internal contents of all 3 issues of the publication.
The interior design of each issue includes a bevy of other typefaces – perhaps the topic of a separate post.
