Not Quite March Madness & We Are Down to the Final 4 (+ 1)

After making a few select purchases I have narrowed the list of collected editions with Batman or Detective Comics down to 4+1:

Batman the Golden Age Omnibus Volume 6

Batman the Golden Age Omnibus Volume 7

Batman the Caped Crusader Volume 4

Batman New Gotham Volume 2

I would still like to find a copy if I can find it at a reasonable price.

Batman Troika

Another book on my list will not be available until April, so I am not technically counting it.

Legends of the Dark Knight, Jose Luis Garcia-Lopez
