"Mississippi" Back Piece 

Banner's famous for the "Mississippi" text across his shoulders. Some of the best lettering in hip-hop (Done by Cartoon). Again, legibility wins out. The clarity of the tattoo provides the punch. 

Xzibit has a solid back text as well (reading "Lost Angel"... also by Cartoon), but Banner's tattoo figures so centrally in his career that it deserves high level recognition.
