Historians make use of a plethora of material as they search for knowledge of the past, always adding new historiography to the existing literature. Only very recently have a few scholars, notably Joseph Witek, sought to examine comic books for what historians might glean from them about history. This study, the first of its kind in relation to comic books – at least as far as published scholarship – is comparable to Robert Darnton’s work, where he studied sixteenth- and seventeenth-century peasantry folktales to find evidence of their thoughts at the time, by looking at the mentalities they conveyed in their tales. Comic books, similar to folktales in their creative nature and fictional context, are no less useful for examining more recent mentalities. This paper examines two mentalities toward homosexuality in the United States through comic books published by Marvel Comics.
