Your second assignment requires you to engage the art of persuasion through the use of striking imagery and limited text in a black and white poster. It is appropriate to reflect on the classic persuasive methods of rhetoric (logos, ethos, and pathos), as rhetoric can be defined as the art of influencing the thought and conduct of an audience[Source: Dictionary.com]. Today, Aristotle's methods hold as much relevance to advertisements and poster design as they do to effective verbal communications.
Consider which of these methods is most suitable to your content by conducting some research on their individual use, purpose, and resulting effect. The sources below should get you started with your search:

Note: The above examples may exhibit characteristics of more than one persuasive method. I have simply chosen the one that seems most evident in order to help categorize.
In helping you to analyze these (and other) images and build your own persuasive poster, reflect on the following questions:
What is it about the visual that grabs your attention first? Why?
How does this image connect to the rest of the visual?
What purpose does this image serve? What do you think the person who created it wanted you to know?
What is this image about? Describe what ideas, emotions, etc.. are portrayed in the image.
What kinds of ideas is this image trying to persuade its audience about?
