Times New Roman by Pedro Javier Arbelaez. This poster in particular is a favorite of mine. I assume this poster goes through the history of Times New Roman. What's great is that Times New Roman is the only typeface used here.
A poster I made for a jazz fusion concert. The lines, colors and effects are quite Art Deco and Cassandre-esque.
I like the slight hidden message in this. Even with this however it is still easy to read and understand. The lettering is formal and smart, as though its a news column piece of text but the clean breaks and slight movement keep it fun and interesting.
