Adam Strange debuted in issues #17–19 of the tryout series Showcase, published November 1958 – March 1959. The first artwork of the character was a cover for Showcase #17 by Murphy Anderson; though Schwartz rejected the drawing and commissioned a new one by Gil Kane, Anderson’s costume design was retained.
In a 1990 limited series, The Man of Two Worlds, Adam learns of the population’s opinion of him and Alanna dies giving birth to their daughter Aleea.
