By William Castille of Lochac, 2004.
Over seventy pages of armorial line art, including over twelve hundred designs suitable for registration in the Society. (It also includes seventy five designs which are unregistrable, along with explanations for the rules they violate — typically marshaling, pretense, and reserved or restricted charges.)
By reproducing period arms using simple outlines and standard clip art, and by grouping arms according to design patterns rather than precedence or name, this collection makes it easier to focus on the elements and arrangements used.
