Go-Go Checks, the checkerboard pattern that ran across the top of every issue for a year and a half was not simply a reflection of the era’s pop-art movement. Since some newsstand racks displayed comics vertically, revealing only the upper portion of a book, the pattern was intended to make DC’s comics stand out and thus, theoretically, increase sales.
