I bought this book when i already had been doing calligraphy for many years. I wish I had found it at the very beginning. It has very clear illustrations that show, by transparencies indicating the sequences of pen strokes, how to build each letter. I taught several people calligraphy using this book, and it was the best for its clarity of presentation.
Moreover, it is a beautiful book to look at, the selection of fonts is particularly nice, and the presentation of the letters doesn't appear to be touched up with a computer after having been done, so that the they look real, something possible for a beginner to actually aim at copying.
I would recommend it as a first book in calligraphy. There are not too many fonts, and they're well-described and attractive. It was also really useful to me, as a more advanced, but not expert, calligrapher.
