I call this a postcard book because that is what this reminds me of but it is actually an accordion folded picture book the size of postcards. On the back of each picture is the name of the building or site in the picture in 6 languages, and inside the back cover is a tourist map of Moscow showing where the sites are located.
The book has 23 sites. Some are single and others are double and at least one is triple. There is no date given but judging by the vehicles this would be in the 1950s. At least after 1952 as one of the pictures is Moscow University, built in 1952. The photos were taken with early color film.
The book is hardback with fabric spine. The condition is excellent for its age. No tears or stains on the photos and only minor wear to the cover corners. From the Foreign Languages Publishing House.
