Did you know that the 1940-era comics in the Batman Franchise hint that both Batman and Robin were a gay couple? Don’t believe me? Have a look at a small collection of panels from Batman comics of that era.
Sleeping together, Tanning together and Skinny-Dipping with Boys..
Horseplay in the shower, carrying Robin in his arm and Pink Batsuits..
and finally, a rather suggestive panel.
