Marital-Bliss Miss! Batman's Long Lost Wife
Going back in history through the DC comics universe it's easy to forget how someone as bad ass as Batman used to be subject to such soap opera-like story lines.
Like this issue of Detective Comics #380 from 1968
Detective Comics Vol 1 380 - DC Comics Database - Wikia: "Bruce Wayne, Dick Grayson, and Alfred are dumbfounded when a woman named Ginny Jenkins appears at their doorstep with the revelation that she is really Bruce’s wife."
What's even weirder is that DC actually has a shirt with this cover in it's catalog.
Get yourself one! Astound your friends!
