These images were taken by Thomas T. Hammond during his trip to the Soviet Union. This specific image features military parading in the recently built New Arbat Street in Moscow, along the <i>Dom Knigi</i> bookstore. The year has been changed to 1972 (the place did not exist in 1964!). It's really odd to see an operating bus with passengers rolling alongside the marching troops and crouds around them.
