The painter's hand-book
The painter's hand-book is a trade reference compiled by Orville Augustus Roorbach and published in New York in 1868, aimed at house and sign painters seeking practical paint formulas. Its pictures are not illustrations but repeated Library of Congress seal endpaper patterns: small olive-green eagle and shield roundels set in a diamond lattice with lettering, usable as a restrained vintage wallpaper or background motif.
