China and pottery marks
A 1920 New York catalogue of china and pottery makers' marks, published by G. Collamore & Co. and drawn from Smithsonian Libraries holdings, for collectors and dealers identifying ceramics. The pictures are stacked rows of small black marks: monograms, crowns, anchors, crossed symbols and geometric squares, all drawn as crisp line and silhouette. A designer could take from them a vocabulary of compact emblems, interlaced initials and heraldic crests suited to logos and monogram work.
