At the restaurants, Wian gave away free comic books featuring the character. Here is an extremely rare example… Big Boy comics number one from 1956. These comics were produced by Timely Comics, which later became Marvel. They were written by Stan Lee and drawn by Bill Everett. Later issues featured the work of Archie comics artist, Dan DeCarlo. Adventures of the Big Boy is one of the longest continuously running comic book lines. It’s still being produced fifty years later.
