Hand Selecta is a  long running project by Christian Acker, which aims to delve in to the art of hand styles. Acker has invited some of the most skilled "taggers" in the world to dissect and discuss their individual letterforms and hopes to release a book charting the development of the book over the years. This baseball and letraset product release with Sabe from Copenhagen is a great little product which shows off the idea of the project perfectly.
