Barack Obama is a great example of how good design is a powerful weapon. Progressively enough, he was not afraid to invest in design, gaining an excellent brand, a powerful communication package and the respect of artists from all over the world. 

I'm a huge fan of Taschen, and a huge fan of what designers from all over the world did for Obama during the most visually-driven presidential campaign in history. So, this book definitely goes on my Christmas list.

About the book from Taschen.com:

Contributors range from prominent graphic and street artists to young up-and-comers. With essays by Spike Lee, Perry-Zucker, and design historian Steven Heller, this outstanding collection serves as a matchless historical document of the widespread visual creativity that helped spur Obama to victory.
