I bought this book in a deal with another concerning Tudor costume. As it was advertised as a colouring book I did not hold out too much hope for its actual usefulness.
However, I was very pleasantly surprised. The book's illustrations are excellent and extremely useful. Never mind it being a colouring book, the black and white line format is clear and good for showing details that you might miss in a painting. With several different classes of Tudor citizen shown for each "slice" of time, the book manages to show a pleasingly broad spectrum of costumes, from peasant to royalty.
As an academic guide the book falls down on its lack of accompanying textual description, but then that is not what it sets out to be. As a purely visual illustration and reference it is excellent.
