Silent but violent is the main catch phrase in my poster, but is normally associated with a different kind of gas! I thought that it fit the description of carbon monoxide perfectly. My poster has a superhero theme. On the top half of the poster, are some objects that can cause carbon monoxide poisoning. Those objects are given a mean appearance, and are made to look like evil villains. The super hero is a carbon monoxide alarm, with a human body. This is to symbolize that a carbon monoxide alarm could help you in your time of need. This poster can raise awareness of carbon monoxide and it's dangers.
