Captain Marvel Jr. character as resembling Tiny Tim as Freddy Freeman, and Peter Pan as Captain Marvel Jr.). Junior, Captain Marvel, and Mary Marvel began appearing together in "The Marvel Family" comic book beginning in 1945. That title and Junior's own ran until 1953, when Fawcett Publications discontinued all the Marvel Family comic books as the result of a lawsuit brought by National Comics (later DC Comics). After Fawcett Comics folded, Captain Marvel Jr. remained unpublished, alongside the rest of the Marvel Family, for years. In 1972, DC Comics purchased the rights to the Marvel Family characters and revived them in a new
Captain Marvel (DC Comics) low-print run in the fall of 1939 as an ashcan copy created for advertising and trademark purposes. Shortly after its printing, however, Fawcett found it could not trademark "Captain Thunder", "Flash Comics", or "Thrill Comics", because all three names were already in use. Consequently, the book was renamed "Whiz Comics", and Fawcett artist Pete Costanza suggested changing Captain Thunder's name to "Captain Marvelous", which the editors shortened to "Captain Marvel". The word balloons in the story were re-lettered to label the hero of the main story as "Captain Marvel". "Whiz Comics" #2 (cover-dated Feb. 1940) was published in late 1939.
