The document summarizes and compares four posters from homeless charities. It analyzes the design elements of each poster, including color schemes, use of imagery versus text, and techniques used to grab attention. The Crisis and SASH posters stand out through highlighted statistics and prominent logos but use only text. The Shelter and Simon on the Streets posters are more eye-catching as they feature disturbing images of homeless people in addition to brief descriptive text. Overall, the posters that incorporate images are assessed as more effective at initially grabbing peoples' attention.
