“The ZAP Show: A Cultural Revolution” is now up at The Society of Illustrators (and runs through May 7, 2016). All the details here.

No one could have known that when struggling illustrator R. Crumb self-published Zap Comix #1 in 1968 and began hawking copies in San Francisco’s Haight-Ashbury district, history would be made.
