A good overview of the subject, I think. It has a nice amount of historical background and context, detailed descriptions and explanations of all aspects of heraldic achievements, including the common meanings of many symbols and designs. There are tons of color and b&w images of various achievements (shields, helmets, full signs, etc.), and examples and discussion of modern applications, such as for states and nations.

It was an entertaining and informative read, and I think it'll be a great reference. ( )
