The American Dollar has not truly been redesigned since about the 1930s. The Dollar ReDe$ign Project invited designers to send in alternatives.
These bank note designs right here are the entries of John Dowling (owner of the London-based Dowling Design & Art Direction). Downling completely stripped them back to its bare bones: type-only with just two elements: a name, and a value denominator.
Any safety issues put aside, this is actually a reasonable entry. Think about it: what more are bank notes than mere promises of money anyways? I could easily live with these ;-)
