I've made this project because I wanted to change standarts that "all German texbooks have to be red-black-yellow". I love book design and i love Germany. That's my little experiment.
I was inspired with Timber framing that's why I used frames on the cover. And for me Germany is a country where all the best funny (and a bit sexual) things happens (for example in Reeperbahn) that's why i changed the letter D to lips.
