I really love this postcard, I think it's quite a clever shot!
Since this is not a touristic card let's talk a little about the famous matryoshka dolls
At one time or another, most of us have been fascinated with the colorfully painted matryoshka or nesting dolls. They come in a variety of sizes, characters and number of dolls nested one inside the other. How did the matryoshka come to be and why? First of all, the name, also spelled matriosha, was a popular name for girls. It is believed that it was derived from the Latin word, mater, which means mother or, more to the point, grandmother. A peasant mother of old Russia often tended to a large family. The largest doll is the grandmother with future generations of dolls tucked inside her. This symbolizes the hope and value of life and the family; the heart an soul of Russian people. While not known for certain, it is commonly agreed that this is the image which resulted in the matryoshka. Traditionally, a matryoshka was given to newborns to wish them a long and prosperous life.
