The folks at Ziller have also produced an amazing series of historic penmanship books. These fascinating books from the late-1800s have been lovingly restored. The information is as relevant today to the modern calligrapher (and non-calligrapher) as when it was written. The At Home with Artistic Penwork (Books 1-5) approach the subject from a variety of directions, from business writing to bird flourishes, while F.W. Tamblyn's Home Instructor in Penmanship may just be the last word on the subject. Improve your penmanship.
