Postcard from China!

Today I got a beautiful panoramic postcard from China! The postcard features a wide view of the skyline of the city of Shanghai at sunset. Shanghai is the largest Chinese city by population and has a population of about 24 million people. It has the world's busiest container port as well. Used were stamps commemorating Airshow China and it also features the special first day cancel for the said stamps. Thanks Hanghui!
