"No Warning Signs" Poster

This poster, while not the most amazing thing out there, is a pretty good example of using a verbal and visual pun within a design. In the reading a pun was described as a "phenomena that one symbol can have two or more meanings, or that two or more symbols can have similar or identical images but different meanings." This uses commonly acknowledged symbols that we use on road ways to stand for warnings or cautions. The poster uses simile to compare the human body and a roadway. The lack of traffic signs (or their presence, in this case, to draw attention) are compared to the lack of symptoms suffered by individuals with kidney disease and the danger either case presents-a danger of not knowing you are in danger, I guess.
