It's all about the Benjamin's baby...and the Frankensteins and Princess Leias and Mr. Ts and the Hugh Hefners. Artist James Charles' latest works come in the form of modified currency: each president's face has been doctored to resemble a pop icon, musician or other artist, and is complete with a caption in the same lettering and materials the U.S. Mint uses on bank notes. In usual art-world fashion, these bills are going for around $700 a pop, so if you purchase one, make sure you don't spend it. [Trendland]
