One Panel #892: Wait, Didn't We Just Do This?

From "Too His Dangerous Doubles" by Otto Binder and Al Carreno, Captain Marvel Jr. #8 (June 1943)

On the same month (at least on the stands, see One Panel last week), both Captain Marvel Adventures and Captain Marvel Jr. had a plot where they've been multiplied. Otto, my dude, having Marv Wolfman levels of writer's block? In this case, there are 8 extra Juniors (none of them on panel) all committing suicide by taking poison pills at the end of the story!
