The Brave and the Bold #78

This 1968 team-up issue of The Brave and the Bold brings together Batman, Wonder Woman, and guest-star Batgirl for a serpentine showdown — the cover by Bob Brown and Mike Esposito says it all, with the snake-suited villain Copperhead coiled menacingly around a fallen Wonder Woman while Batman and Batgirl look on in alarm, surrounded by a writhing mass of reptiles against a vivid purple backdrop. The title "In the Coils of Copperhead!" perfectly captures the peril splashed across that striking image. Three of DC's finest heroes facing one very dangerous villain makes this a memorable entry in Brave and the Bold's celebrated team-up run.
