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 1956 to September 1970 (suspending publication with issue #93), and then was revived for eleven issues from August 1977 to September 1978.
