Captain Marvel #1, May 1968
Tonight’s cover image from the Lizard Collection: a “very fine” to “near mint” copy of Captain Marvel #1, originally published in May 1968. Wikipedia has some interesting details on the unique history of this book: Captain Marvel (Marvel Comics).
Following a trial in which DC Comics sued Fawcett Comics for breach of copyright, the latter stopped publishing Captain Marvel. In the late sixties Marvel gained the trademark “Captain Marvel” with their first series, forcing DC to call their Captain Marvel comic book Shazam!, but to retain the trademark Marvel had to publish a Captain Marvel title every year or two since leading to a number of ongoing series, limited series and one-shots featuring a range of characters using the Captain Marvel alias.
