2011 MARKS THE THIRTIETH ANNIVERSARY of the release of the Call of Cthulhu roleplaying game. To celebrate this important and rare occasion in our Adventure Gaming industry, Chaosium is proud to offer a special binding of the current edition (6th edition) of the Call of Cthulhu rulebook. This 320-page book features thick (3 mm) leatherette hard-covers with the front cover and spine stamped with luxurious gold foil. The interior pages are printed in black ink, on 90 gsm matte art paper. The binding is thread sewn, square backed. Each book is individually shrink-wrapped, with the barcode stickered onto the wrapping so as to not mar the book cover.
