Universo de emociones (universe of emotion) Like the idea of mixture with maps and colored overlapping circles as categories. Gorgeous layout, clear and structured visualization, amazing detail, mind-blowing information, just love it!
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.
