Doc Johnson’s Adult World — Philadelphia, PA (c. 1970s–1990s) A Center City fixture with neon bravado and aisle after aisle of “therapeutic aids,” Doc Johnson’s Adult World was the equal-opportunity emporium where straights and gays alike shopped side by side—part curiosity shop, part community landmark. Known around Arch Street for its window displays and late hours, it sat in the slipstream of Philly’s gritty downtown nightlife, supplying everything from magazines to novelties to anyone bold enough to walk in.
