20-Sided Die Patent T-Shirt


In 1974, visionary game designer Gary Gygax launched the wildly-influential Dungeons and Dragons at Gencon, the fantasy and tabletop gaming convention he founded six years prior. As part of the design, Gygax re-introduced a die that has existed since Roman times – the icosahedron – or, the 20-sided die. 

Given its long history, a trip to the patent office never crossed Gygax’s mind. The patent was eventually filed on Aug. 12, 1997, under the dubious claim that it would aid the operation of state lotteries... but we all know who really earned the kudos.

Printed on 100% cotton Next Level 3600 and 3900 gold tees with printed interior label. Available in unisex sizes S-3XL and women's sizes S-2XL.
