Keratol was a binding material used briefly in the Modern Library series with the 1928 gift set. It was shiny with geometric patterns (one Mailing List member said it reminded him of shower curtains); otherwise it looked like the same binding style as Toledano style 4.
It was used on only three titles: Cellini's Autobiography of Benvenuto Cellini, Merejkowski's Romance of Leonardo Da Vinci, and Symonds' Life of Michelangelo. Each title was bound in a different color keratol—turquoise, orange, and chartreuse.
For detailed illustrated discussions of binding types, see the Toledano Guide (reviewed elsewhere on ModernLib). For a more limited treatment, see Quick Guide to Regular Binding Styles.
