Swamp Thing made his first appearance in DC’s House of Secrets #92 (July, 1971).  It was a stand-alone story that was set in the early 20th century.  It did not have much in common with the Swamp Thing that was all know today but the issue will always be remembered for its cover, which was drawn by Bernie Wrightson.  The girl who is coming her hair while Swamp Thing approaches was modeled on Louise Jones, who would later be known as Louise Simonson and would become an important comic book writer in her own right.
