The evolution of airplanes and a sliver of the moon are in the sky. There are rolling hills each representing 20 year increments from 1875 to 2005. A woman walking with a baby carriage, a man on a bicycle, a couple in a car, and the Eiffel Tower personify 1875-1895. A soldier with a rifle on his shoulder, a woman holding a baby while standing with her mother, and a movie camera illustrate 1905-1925. A soldier in a tank, a television, a shortwave radio, and an astronaut symbolize 1945-1965. 1985-2005 is typified by a computer and a grey haired person sitting in a wing chair.
