DC comics Earth 1889/Earth 19~
Earth 1889 (later re-designated as Earth 19) is the home to the first ever DC Elseworlds, specifically the setting of Batman: Gotham by Gaslight
Released in 1989 the first Gotham by Gaslight, saw the Cowled Crusader take on none-other than Jack the Ripper:
There was a sequel (set in 1892): Batman: Master of the Future
This time Batman took the airship piloting Alexander LeRoi (who bore more than a passing resemblance to Jules Verne’s Rubor the Conqueror, and thus Vincent Price).
The most recent appearance of Earth-19 was with the publishing of Countdown Presents: The Search for Ray Palmer: Gotham by Gaslight
This time versions of Wonder Girl, Green Lantern and Robin (as the Challengers from Beyond) encounter the gaslight Blue Beetle and take on Man-Bat.
