DC One Million #1A (1998)

One Million - Riders on the Storm
The Justice Legion A, a group from the future, have arrived in 1998 to gather that era's Justice League to celebrate the return of Superman Prime, the original Kal-El, to the 853rd Century. (This would be right around the time DC will first publish the millionth issue of one of their titles, assuming monthly scheduled are maintained that long.) However, someone has a plan to disrupt that celebration.
