Frank W. Bolle (born June 23, 1924) is an American comic strip artist, comic book artist and illustrator, best known as the longtime artist of the newspaper strips Winnie Winkle and The Heart of Juliet Jones; for stints on the comic books Tim Holt and Doctor Solar, Man of the Atom; and as an illustrator for the Boy Scouts of America magazine Boys' Life for 18 years. With an unknown writer, he co-created the masked, Old West comic-book heroine the Black Phantom. Bolle sometimes used the pen name FWB and, at least once, F. L. Blake. Bolle broke into comics in 1943, drawing backgrounds for Funnies Inc., one of a handful of "packagers" that supplied content to publishers entering the fledgling medium of comic books. His first known credits are penciling and inking two "Terry Vance" detective features for Timely Comics, the precursor of Marvel Comics, in Marvel Mystery Comics #47–48 (cover-dated Sept.-Oct. 1943). He served in World War II, and It is unclear if the small number of Bolle stories that appear in comics from U.S. Camera, Rural Home, and Green Publishing through 1946 were done during the war or were inventory from before his service. His comics output became regular soon afterward with a "Freddy Freshman" story in Fawcett Comics' Captain Marvel Jr. #46 (Feb. 1947) and work in Crown Comics from the publisher McCombs from 1947 to 1948.
