We were tempted to give this award to Zombie's House of Curiosities on University in St. Paul for its unparalleled kitsch value: It's a classic head shop that carries pipes, water bongs, throwing stars, and—in a back room—uproariously trashy smut. But then we stumbled across the Adult Only Superstore on Washington Avenue and our mouths hit the floor. It's a new store—so new as to have an unlisted phone number and, as of yet, no credit-card machine. But this smallish storefront business puts larger competitors to shame with its dazzling variety of merchandise. This is a connoisseur's sex shop, as evidenced by its impressive selection of '70s-era adult movies, many starring the brassy, lecherous Georgina Spelvin, who was 37 when she came to prominence as a performer, and looked it. Also on hand, scattered among the more mainstream products: nonfiction books about the early years of the adult industry, including a bio of Russ Meyers; copies of Found magazine's adult counterpart, Dirty Found; and number of tacky paperback books with garish illustrations on their covers and titles such as I'll Whip Your Ass and Serve Your Mistress. This is a store that evidently views erotica as an adventure, and a surprisingly fun one. After all, among their inflatable sex dolls is one called "Fatty Patty" and another, named "G.I.L.F," whose dubious pleasures we dare not describe.
