After DC Comics in 1956 ushered in the period fans and historians call the Silver Age of Comic Books, by reimagining such Golden Age superheroes as the Flash and Green Lantern for modern audiences, Andru and Esposito began a long run on DC's "Wonder Woman". They drew the long-running superheroine's title from issues #98–171 (May 1958 – August 1967), "defining her look during boom period". As well, with writer-editor Robert Kanigher, they co-created the robot superheroes the Metal Men in "Showcase" #37 (April 1962), going on to draw the first 29 issues of the lighthearted series "Metal Men", from 1963 to 1968. Esposito considered the series "the best idea [Kanigher had done," specifying that, "Bob left the character design up to Ross and myself, under his supervision, of course."
