This is probably the Intourist tour guide on their bus to Dubna. I originally thought this was in London prior to flying to Moscow, but was corrected by Flickr user mixtara.
Taken by my grandfather David C. Cook on the way to a visit to Moscow for a meeting of the International Electrotechnical Commission. Scanned from an unlabeled Kodachrome slide numbered 4 in a slide cartridge marked "Russia".
