As stated in Mark James Estren's "A History of Underground Comics," this was actually published after Zap #2 came out in 1968. The artwork for this issue was lost after the publisher who had it moved to India. Luckily, Crumb had made xeroxes which he managed to locate months later. Crumb did get the original artwork back several years later.
