The document summarizes and compares four posters for homeless charities. It discusses the design techniques used in each poster, including color schemes, use of imagery versus text, and ways they draw attention and convey their message. The SASH and Crisis posters stand out less but rely primarily on text in basic color schemes. The Shelter poster uses a darker color scheme but its image of a newspaper suit grabs attention. The Simon on the Streets poster also uses impactful imagery to elicit an emotional response along with a moderate amount of text. Overall, the document evaluates how each poster communicates its message through visual design.
