This pair of colorful posters was published in 1993 by TSR, Inc. to accompany their new interstellar campaign setting for Advanced Dungeons & Dragons – Spelljammer. The fantastical outer space environment is detailed across two sheets. The first presents a planetary display map identifying celestial bodies, hazards, and habitable planets. The second sheet provides diagrams of Highport (a spaceport) and the Antilan Crystal Citadel. Tactical Studies Rules (TSR) was founded in Lake Geneva, Wisconsin in 1973 by Gary Gygax and Don Kaye to publish their wargames, quickly pivoting to focus on their groundbreaking tabletop role-playing game, Dungeons & Dragons. The immense success of D&D in the late 1970s transformed the small company into a major force in the hobby game industry, leading to rapid expansion, a wide range of new products, and the launch of iconic fantasy campaign settings like Dragonlance, Ravenloft, and Forgotten Realms.
