Help finding a scan

Hello all,
I'm a new guy here but I'm looking for a scan but I cannot for the life of me.
I believe its a Frank Miller Graphic novel (but not sure).
Basically Batman and Joker are laying on the ground in the rain both dead. after a long battle.
Its something to do with Batman and Joker being two sides of the same coin.

I really appreciate any help I can get, I know its not much to go off of and Ive been looking for a while. Im pretty sure its from one of the big graphic novels.
