References in Justice Society of America (vol. 4) #4 to Per Degaton’s history in both All-Star Comics #35 (Jun–Jul 1947) and JSA #72 (Jun 2005).
We finally get to meet the Justice Society of the present-time DCU in this issue (although it’s still reading closer to a future-Huntress book than I’d personally prefer). Apparently Beth Chapel and Yolanda Montez were resurrected as a prelude to the Lazarus Planet events; they were originally killed back in Eclipso #13 (Nov 1993). (How this fits with Doomsday Clock #12 is left as an exercise for a reader who reads more event minis than I do.)
