mottled edges
A form of edge decoration produced by daubing
color lightly over the edges of a book, generally
by means of a sponge which leaves its natural
markings on the edges. The edges may be colored
over first, or the mottling may be applied
directly to the white edges. Red and black are
frequently used combinations. Mottled edges are
found mainly on large blankbooks but seldom on
letterpress bindings. (256 )
