Tibet

Really nice colorful stamps and an awesome postmark! 

This is a really cool card from Jokhang Monastery in Tibet. 

Entering Tibet you feel as though you've entered an entirely different world. The traditional Tibetan culture, though heavily diluted recently by government-sponsored migrations of Han and Hui Chinese, remains strong.
Tibet spans the world's largest and, with average heights of over 4,000 m, also the world's highest plateau, consequently Tibet is often referred to as the "Roof of the World". Parts of the region (northwestern region) are so remote they remain uninhabited to this day.
Tourism to Tibet is strictly controlled by the Chinese government. As of 2009, the previous "backpacker" tours, which included the permit and a couple of nights stay in Lhasa is no longer an option and all travelers must stay with an organized trip the entire time they are in Tibet. That means you will not be allowed to travel on an independent basis and you will be presented Tibet from an official Han Chinese government sponsored perspective.
