The Little Know-It-All from Gestalten is either a desk reference or a toilet book, depending on your reading preferences. With the tag-line of “Common Sense for Designers” it’s a book full of all the things you didn’t bother to pay attention to in design school and wish you had. Forgotten your colour theory? Can’t remember paper sizes? Don’t know your flexo from your gravure printing? This is the book for you.
