Check out Bush Leaguers: Cartoonists Take On The White House, a collection of cartoons from the Association of American Editorial Cartoonists.
From the forward:
"The AAEC, in honor of it's 50th anniversary and in conjunction with the American University Museum at the Katzen Arts Center, presents this rare collection of political cartoons about George W. Bush and his most trusted advisors. It contains the complete exhibit, "Bush Leaguers: Cartoonists Take On The White House", which was on display at the American University Museum in Washington, D.C. in honor of the AAEC's 50th anniversary. Over 80 cartoonists from newspapers across the country, including several Pulitzer Prize winners, have contributed their best cartoons depicting George W. Bush, Dick Cheney, Karl Rove, Donald Rumsfeld, Condoleezza Rice, and more.
The above cartoon was my contribution to the exhibit and appears in the book.
