DC Comics insert previews were 16-page comic book stories inserted into issues of existing DC Comics series to promote new series usually debuting the next month. Running from 1980 to 1985, they consisted of a front cover, 14 pages of story, and a back cover that depicted the cover of the actual first issue. The addition of the insert did not entail an increase in the price of the comic book, and the cover copy called the insert "a special free 16-page comic!"
