The rhythm of life
The Rhythm of Life is a 1915 New Thought treatise by Charles Brodie Patterson, published in New York by Thomas Y. Crowell, on music, colour and rhythm as aids to health and wellbeing. The only picture is a Library of Congress bookplate-style emblem: an eagle with spread wings above a ring lettered LIBRARY OF CONGRESS around a central 1800 medallion, a plain engraved seal with no bearing on the book's subject. A designer might take from it the crisp, symmetrical composition of a ring seal with an eagle crest.
