For Africa

President George Bush, Sen. Barack Obama, Madonna, Oprah Winfrey, and Chris Rock are but a handful of 15 others to make it onto the 20 covers of Vanity Fair's historic Africa Issue.

Edited by Bono, the July 2007 issue includes articles written by journalists such as William Langewiesche, Sebastian Junger, and Christopher Hitchens, among others, that focus on some of the more promising solutions facing Africa today.

The covers, "a visual chain letter spreading the message from person to person to person," were shot by famed photographer Annie Liebovitz.

Madonna's cover co-stars are Academy Award nominee Djimon Hounsou and Maya Angelou.
