Batman may have plenty of modern movies, games, and TV shows based around him and his adventures, but the Caped Crusader first appeared in the pages of DC comic books many, many years ago. Batman would make his debut in the 27th issue of Detective Comics, released all the way back in 1939, but since then, he's had plenty of stories covering his many heroic escapades within, and even outside of Gotham City, which has also resulted in plenty of stunning comic covers which have since become iconic.
