While we already have an appreciation thread for Batman, this one is a bit more specialized: it's designed to honor / celebrate the version of Batman who originally appeared in comic books during the late 1930s, the 1940s, and into the early years of the 1950s, prior to the changeover from "Golden Age" to the "Silver Age" version (a point in time which I don't think has clearly been defined for Batman as to a specific title / issue #).
Once the "Silver Age" version became the focus for Batman stories later in the 1950s, the Golden Age version was basically sidelined for a while. An adult version of Robin took over for Batman in the Justice Society of America (who during the Silver Age were revealed to still be somewhat active on a separate Earth, called "Earth-2" or "Earth-Two"), and it was also later revealed that the Golden Age Batman had married Catwoman (Selina Kyle), had a daughter (Helena, who became The Huntress), and eventually became the Police Commissioner for Gotham City (on Earth-2, of course).
His death occurred during an adventure of the Justice Society of America in 1979,
but there were still some "untold stories" of Batman's past that would be published from time to time. The origin story for Golden Age Batman was included in Secret Origins #6 (from 1986),
and the ghost of the (former Earth-2) Batman even played a role in an adventure of the JSA back in 2006!
(More on that one in a future post!)
