For those of you not completely familiar with Earth-2, check in with Wikipedia
First appearing in The Flash #123 (1961), Earth Two was created to explain how Golden Age versions of characters such as The Flash could appear in stories with their Silver Age counterparts. Its continuity includes Pre-Crisis DC Golden Age heroes, including the Justice Society of America, whose careers began at the dawn of World War II, concurrently with their first appearances in comics. Earth-Two, along with the five surviving Earths of the DC Multiverse, are merged into one in the 1985 miniseries Crisis on Infinite Earths.
