Shadow of the Bat The Last Arkham set

The Shadow Of The Bat comics was a series containing 96 issues release beginning in 1996 and ending in the year 2000. The primary storylines of the series revolved around examining the psyche of different Batman characters. 

My favorite issues from this series gives deep insight into one of my favorite Batman villains: The Joker. The Joker story is told in Shadow of The Bat issues 37-38 and give a brief recap of The Joker's origin- expanding on the events of The Killing Joke
