Comics Should Be Good has a feature on the top 10 Pieta covers — covers inspired by Michelangelo’s statue, Pietà , of Mary holding the lifeless body of Jesus. The most famous of these covers is probably George Pérez’ cover for Crisis on Infinite Earths #7, the death of Supergirl.
One Flash cover made the cut: Flash v.1 #305, in which Barry Allen and Jay Garrick each hold their dead wives. (It turned out Joan wasn’t actually dead. And Iris got better…eventually.)
There’s at least one more Flash cover that fits the bill: The full cover for Flash: The Fastest Man Alive #13, featuring the Black Flash carrying the lifeless body of Bart Allen.
This was the cover that set me looking for examples of dead Flash covers last year — and it’s amazing how many there are!
