The project my Art Direction class is working on right now is to make a typography-driven print piece for a PSA about texting and driving. Working on it has made me realize how odd typography is as a medium, and how much I love it. The form vs. function balance is so interesting, especially in advertising-driven designs; when does readability hit the back burner in favor of shape, texture, and other elements of a really captivating image? It seems like there are never any concrete answers to that question because it depends on so many other factors, like audience, and where the design is going to be seen. Here are some great examples of typography posters for a variety of different purposes; some of them are more readable than others, but all of them seem to have struck a good balance between readable an aesthetically pleasing.
