Tuvan Stamps

People who collected stamps in the 1950's all were familiar with stamps like the ones below. Modern catalogs like Scott's don't recognize all of them as actual postage issues, so they have tended to be inexpensive, and the shapes and designs are intriguing. Tuva today is a Russian republic, adjacent to Mongolia. The people speak a language which is quite similar to Turkish and their religion is a branch of Tibetan Buddhism.
