Superman/Batman Vol 04 TP

Superman, Batman and the Justice League realize that Kryptonite is a more widespread problem than they believed in these stories from SUPERMAN/BATMAN #37-49. The world’s finest heroes must hunt down what seems to be an endless supply of Kryptonite across the globe-but in order to rid the world of its Kryptonite infestation, Superman may be forced to cripple entire cultures that have grown to depend on it.
