Kayo boasts unexpurgated editions (many of them first editions) of some of the lowest-brow literature this side of the men's room. The material mainly hails from annals both obscure and lurid, from the 1930s to the 1970s. Most of the items are more depraved than an H.P. Lovecraft book. Titles by the likes of David Goodis, Ed Wood, and Peter Rabe share shelf space with Mad magazines and monster comics. The store is also a veritable cornucopia of collectors' items; its two floors are crammed with comic books, rare vintage magazines, hard-boiled fiction, and seedy sci-fi. Considering that Kayo has helmed counterculture lit in S.F. for the last 11 years, it's no wonder sleaze lovers like director John Waters get their regular dose of smut right here.
