Detective Comics #138 (1948)

Detective Comics #138, true believers, features one of the most iconic match-ups of all time: Batman vs. Joker! In "THE INVISIBLE CRIMES," the Clown Prince of Crime steals an elixir that makes him invisible, causing chaos and confusion throughout Gotham City. But don't count out the Dark Knight just yet, as he uses his detective skills and batarangs to stop the Joker in his tracks. But that's not all, as the issue also includes "THE INSIDE STORY OF THE ROBOTMAN," in which our hero gets broken into pieces and the police must figure out how to put him back together. It's a race against time, true believers, as they search for instructions on how to rebuild Robotman. And if that's not enough, "SHORTY MEETS THE CHAMP" and "THE MYSTERY OF THE MARY CELESTE 2" (featuring the Boy Commandoes) round out this wonderful issue. So, if you're looking for action, adventure, and a bit of mystery, be sure to add Detective Comics #138 to your collection, and remember, don't make us angry, you wouldn't like us when we're angry - no wait, that's the wrong hero, Excelsior!
