Detective Comics #66 (1942)

In Detective Comics #66, we witness the first appearance of Harvey Dent, famously known as Two-Face. As he's prosecuting a criminal trial, acid is thrown at him and causes him to become a master criminal obsessed with the number two. Dent decides his fate by flipping a double-headed silver dollar - if it lands on the clean side, he waits for his plastic surgeon, but if the scarred side appears, he chooses a life of crime. Batman and Robin try to thwart his plans, but a bullet meant for Robin ricochets and hits the bus driver, causing chaos. Two-face holds Batman at gunpoint and flips his coin, but it lands on its edge, leaving him unable to decide whether to kill the Caped Crusader. The story continues in Detective Comics #68. Along with this thrilling tale, the comic includes other exciting stories, such as Air Wave's The Adventure of The Shooting Spooks. If you're a fan of classic comics and love hearing about the origins of iconic characters like Two-Face, this issue of Detective Comics is definitely worth reading!
