Re: Who drew the comics?
As far as I know, David Berg never drew anything. He was, however, very involved with telling the artists what and how to draw. The cult had (and still has) many artists that contributed towards their publications. In the early days (1970s), they used them primarily for covers of Berg's articles. Around that time, Berg wanted all of his writings illustrated. At first, the primary audience was adults, but later they started producing them for children (see:
True Komix).
Here is a list of cult artist (past and present):
