In honor of the 20th Anniversary of the award-winning Call Of Cthulhu RPG, Chaosium is proud to release a premium, bonded leather-bound edition of the core rulebook. This special limited edition features high-quality paper stock, a new interior layout designed to evoke that "ancient tome" look and feel, sienna ink, and a durable Smythe-sewn binding that collectively make this 300-page work of art the one edition that every Cthulhu player and Keeper will have to have. It would also make a stunning prop for Cthulhu Live. This is a once-in-a-lifetime gift, a very limited edition that will never be reprinted.
