At the first sight of this picture , I didn't realize what it actually meaned. Then I see the cigarette in the man's hand ,and a prist and some people looking at him through the hole . I suddently realize what it wants to tell us . It is kind of a poster which advise people to stop smoking . When we smoke , we are likely to be a dead man in a tomb because cigarette is killing us . It is impressive . 

The image shows us the sight at an angle of looking up view , which makes us feel like part of the scene as a smoker . And in this way , it persuade us to stop smoking.
