This is a photo collection of World Heritage sites. It's a complete set of 12 volumes with a supplementary booklet. The spines are slightly discolored, but the sides and contents are in very good condition. I purchased it and stored it carefully, hardly ever opening it. It's filled with beautiful photos that I could never take myself. Those who have traveled abroad will feel nostalgic for their trips, and those who haven't can feel like they've traveled. Perfect for those who love travel and World Heritage sites.
