John Byrne (comics)
In early 1980, Byrne did his first work for DC Comics, penciling the first issue of "The Untold Legend of the Batman" miniseries. Byrne had always wanted to draw "Batman", and had a three-month window of time during which he was not under contract to Marvel. Hearing about the "Untold Legend" series, Byrne contacted editor Paul Levitz to express interest. DC took him up on his offer, but it was not until the second month of his three-month window that Byrne received the plot for the first issue. Byrne told Levitz that he would not be able to finish the project due to time constraints despite DC then allegedly offering Byrne double his Marvel pay rate, after initially saying they could not match his Marvel rate. Byrne penciled the first issue, which was inked by Jim Aparo after being intended for Terry Austin. This experience soured Byrne on DC for quite some time.
