Existing comment: Showcase presents Metal Men
#38 (June 1962)
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 ongoing titles. The Metal Men appeared in three issues of Showcase (#38-40, June-October 1962) and proved popular enough to warrant a reappearance in their own eponymous title.
