Can’t say that I blame Fortune Magazine for rejecting a commissioned cover by Chris Ware. The May 2010 cover depicts the United States with smaller images that include “Guantanamo Bay prisoners, Mexican factory workers, and a few potshots at business execs and money-grubbing politicians.”
If the story was focused or mentioned these items (I’ve not read the cover-story), it seems fair game to include them. If not, it seems inappropriate for the artist to toss in these editorialize issues. See enlarged images of the art in question on The Chicagoist.com.
