Showcase has been the title of several comic anthology series published by DC Comics. The general theme of these series has been to feature new and minor characters as a way to gauge reader interest in them, without the difficulty and risk of featuring “untested” characters in their own ongoing titles. The original series ran from March-April 1956 to September 1970 suspending publication with issue #93, and then was revived for eleven issues from August 1977 to September 1978.
