This "book" is simply blank white pages with black outlines of typical lead patterns used in stained glass windows. There are no examples of colour, illustrations, history, techniques or even figure titles. This may be of use if you happen to find an exact outline for a project of your own and already understand the techniques, history etc, but I can see little value in this. There are far better texts available that include full colour photographs, and written detail on period stained glass. One to miss.
