First and only appearance of the 2nd Crimson Avenger. His predecessor (Lee Walter Travis) debuted in Detective Comics (DC, 1937 series) #20. Interestingly, Crimson Avenger states that he has taken the name of a former lawman, presumably the 1930's version.
Previously appeared in November 1962 issues.
