Children can learn to count to ten with numbers shown with familiar city objects, including skyscrapers, a bag of leaves, and a subway car.

Color has the power to inspire and delight. The playful photographs here invite youngsters on an international urban journey with color as their guide --- from London's famous red double-deckers to New York City's shiny black limousines to Rio de Janeiro's multicolored playgrounds. The ten colors featured are each clearly presented in a main photograph and in a smaller focus image.
