Dungeons & Dragons required the use of five polyhedral dice when it first came out, and back then in 1974, the only place TSR could acquire them was from Creative Publications. But theirs were not the first set of plastic Platonic solids marketed in America as dice. A decade before, Advertising Attractions, Inc. of New York sold the Zazz "Polyspheres" game, an invention of Fredda Sydney Sieve, which featured all five polyhedra with numbered faces. Today, we're going to look a bit at Sieve and how she came to make these plastic polyhedra.
