Anatomy of Cuban Design

I found this design poster for the IAAF World Championship in Athletics http://www.icograda.org/feature/galleria/galleria417.htm. Set back at its simplicity but at the same time complexity of the piece, I was amazed at how his use of color and graphics chosen completely bring this design together. His theme of shapes, squares and circles mainly along with lines, unify the design along with the type chosen. The rings in the center give an olympic feel to the event that is taking place.
