Heroes Against Hunger

Superman, Batman and Lex Luthor try to stop hunger in Ethiopia. They face the Master, who they believe to be the main culprit. But the reasons are different.
Heroes Against Hunger featuring Superman and Batman was published by DC and like the earlier Marvel benefit project (Heroes for Hope) featured many top comics creators into several 2-page chapters. It was an all-star benefit book for African famine relief and recovery. (From DCWikia.com)
