Font Book is an experimental project demonstrating three forms of type—regular, italic and bold—by using different binding methods. I selected three signs to symbolize the forms: the sun and the moon show up regularly, the fluidity of italic is similar to water, and the bold fonts are as stable as mountains. 28 pages (regular); 56 pages (italic); 90 pages (bold); 7 1/4 x 9 1/4, 4-color, saddle stitch with thread (regular); coptic stitch (italic and bold).
