Zap Comix was a series of comic zines initiated by Robert Crumb in 1968 to showcase his own work. The series is considered to have started the surge of underground comics in the 1960s and 1970s. Zap Comix saw 17 issues, the last having been published as late as 2014. The first issue was sold on the streets of San Francisco’s Haight-Ashbury district and aimed at the district’s alternative crowd, its adult and psychedelic contents free of restraints imposed by censorship of the Comics Code Authority. For the second issue Crumb invited fellow-artists Rick Griffin, S. Clay Wilson and Victor Moscose to contribute to Zap Comix No.2. The four of them would remain the core of the Zap artists throughout the history of zine.
In late 1968, shortly before Zap #3 was to be published, Crumb found Xerox copies of the missing pages from the original Zap #1, which (according to Victor Moscoso) successfully captured the linework but not the solid blacks. After being re-inked by Crumb, those strips subsequently appeared as Zap #0. Thus Zap #0 became the third in the series, even though it was drawn before #1 in 1967.
This particular copy of Zap #0 was printed by Apex Novelty, San Francisco (Don Donahue) in a 3rd printing in 1969 and is in fine condition with only the slightest wear and yellowing of the pages.
