Super Mario Bros Special Edition #1 (Valiant 1990) CGC 9.8 Super Mario Brothers. Highest CGC grade known and only 90 copies in CGC inventory. One regular sized book with cardboard stiffener weighs about 7-8 ounces. Large trade paperbacks are more like 26-30 ounces. I have thousands of other comics mostly from the late 70's to late 80's.
