11. Martin: 1000 Showcard Layouts. 1928, 1930, 1984.

An amazing book if only from the realization of the effort it took to produce it! H.C. Martin, a frequent contributor to Signs of the Times Magazine, was commissioned to produce a book of 1000 showcard layouts specifically to be used in a book. He had a very large following of readers and fans at the time and this book filled their needs and expectations. While each layout might not be earth-shattering, they show a keen understanding of balance, dominance, and rhythm popular with the showcard craft.

	12. Welo: Studio Handbook. 1927 (1935).
Samuel Welo seemed to have picked up where Martin left off. Actually this book would have been produced about the same time and they share similar styles of lettering and layout. This book features numerous hand-lettered alphabets and several pages of ornaments, dingbats, and panel layouts.

13. Herberling: Basic Lettering. 1922.

W.A. Heberling was the Instructor of Sign, Scene, and Pictorial Painting at the Mooseheart Vocational Institute in Mooseheart, IL. This book was also used as a textbook, taking beginners through the basics right up to painted pictorial billboards. In several places, this books resembles illustrations in the Imelli book, but not quite as high of quality across the board. It is probably not as common as books from some of the larger trade schools.

	14. Kelly: The Expert Sign Painter. 1910 (1922).
Probably the least illustrated of all the books in this list. Ashmun Kelly wrote this book for the technical side of the sign trade audience. He explains some of the most complex elements and techniques of the trade including gilding, mirroring, frosting, and embossing. For a contemporary sign maker curious as to how things were done almost 100 years ago, this book is a must.

15. LeBlanc: Gold Leaf Techniques. 1961 (plus numerous reprints).

Raymond J. LeBlanc wrote the quintessential book on working with goldleaf of the time. With a few revisions to allow for updated materials, most of the techniques described in his first book are still being used today. This book would have been found in almost every sign kit of any gilder since that period. While there are some very interesting photographs of LeBlanc's work in the book, the technical writing places it as a must have book and probably most read of any book in this list.
