Swamp Thing #1 (1972)

Swamp Thing, created by Len Wein and Bernie Wrightson, presents a mixture of the macabre and marvelous in the character of scientist Alec Holland who finds himself transformed into the titular muck-encrusted hero in this first issue from 1972. Centered in the swamps of Louisiana, the bayou hero would undergo major transformations at the hands of successive artists like Gerry Conway and Alan Moore. Nevertheless, it is Bernie Wrightson's orignal concept art shown here which summarizes the fusion of humanity and nature that would be the series's longstanding draw.
