Centroid envy

A scrapbook of original designs and proof prints for early Victorian bindings done by R. A. Harrison, ca. 1840s.
Along with sketches for roundels and decorative borders, product labels, and a caricature, are a number of proof sheets for bindings, that retain, remarkably, their intense colors, making available to bibliographers for this period of book production, some of the most faithful hues (which can be described using the Centroid Color Chart).
