Batman heads to to the “Latin American” country of Mantegua in Batman 56 (Dec/Jan 49/50), as he trains a Batman for that nation.
David V. Reed joins Sprang and Paris on this story, as the ambassador of Mantegua begs Batman’s help in dealing with a bandit leader, El Papagayo. Reference is made to the country having “pampas,” which I believe means it must be on the border of Argentina.
Batman decides to train a knock-off for the region. He holds auditions, and winds up choosing a man who is secretly working for El Papagayo. He trains him, outfits him in a Bat-costume with a serape, puts a mask on the guy’s horse and christens him Bat-Hombre.
It takes Batman a shamefully long time to figure out that Bat-Hombre is in league with the bad guy, but he eventually does, and then impersonates him to take down El Papagayo.
A few years down the road we would meet the Gaucho, the Batman of Argentina. I would say that hero was inspired by Batman’s actions in this story.
Finger, Sprang and Paris spin a Penguin story in this issue, which has him fall for a revenge plot by a criminal he squealed on while in prison. The man challenges the Penguin to commit a series of crimes, for a reward that turns out to be valueless.
It’s not the best Penguin story, but there is a weird looking egg-trap that he uses on Batman and Robin that stands out.
