The stamps of the 1920s were dominated by the Series of 1922, the first new design of definitive stamps to appear in a generation. The lower values mostly depicted various presidents, with the 5c particularly intended as a memorial of the recently deceased Theodore Roosevelt, while the higher values included an "American Indian" (Hollow Horn Bear), the Statue of Liberty, Golden Gate (without the bridge, which had yet to be built), Niagara Falls, a bison, the Lincoln Memorial and so forth. Higher values of the series (from 17¢ through $5) were differentiated from the cheaper stamps by being designed in horizontal (landscape) rather than vertical format, an idea carried over from the "big Bens" of the Washington-Franklin series.
