The company's comics include the first 3-D comic book, "Three Dimension Comics" #1 (Sept. 1953 oversize format, Oct. 1953 standard-size reprint), featuring the Terrytoons movie-cartoon character Mighty Mouse. According to Joe Kubert, co-creator with the brothers Norman Maurer and Leonard Maurer, it sold an exceptional 1.2 million copies at 25 cents apiece at a time when comics cost a dime. St. John also published the second 3-D comic, the aptly named "3-D Comics", the single issue of which incongruously billed itself as "World's First!"
