2". Obverse reads "The Time Souvenir Company New York." Has a little dial that moves around w/different numbers on it for different times of the day and points to different cities of the world and tells you what time it is there when it's another time in the U.S. or wherever you're looking. Reverse has a picture of Dewey on a star blue flag and reads "The Nation's Hero Admiral Dewey." Along the edge is "Whitehead & Hoag Company Manufacturers For The Time Souvenir Company New York." Very clever, rare and the first we've seen. From the Hake collection. See next item.
