The Vigilante Trailer

The original Vigilante (Greg Saunders) was most recently seen in Justice League cartoons from the early 2000s as a side character but in the mid 20th century this motorcycle riding, whip cracking gunslinger was such a popular comic book character he starred in his own 15 episode Columbia Pictures serial called Vigilante: Fighting Hero of the West starring Ralph Byrd.

Much different from the 1990s character Adrien Chase this version was a wholesome slice of Americana. This trailer for the serial is Public Domain and perhaps all that's left of the project.
