AN EXCEPTIONALLY RARE 3¢ 1869 ISSUE TRANSATLANTIC PRINTED MATTER USE TO PRUSSIA.
Unlike the case with letter postage, rates for printed matter became higher and more complex under the US-NGU Convention. Base rates for newspapers up to 4 oz. were 3o by direct mail and 4¢ by closed mail. Circulars were considered "book-packets" up to 4 oz. and were charged 6¢ by direct mail and 8¢ by closed. That lasted until late 1870, when a special "book-packet" up to 1 oz. rate was introduced for circulars and charged 2¢ for direct mail and 3¢ for closed.
