A matryoshka dollalso known as Russian nesting/nested doll, refers to a set of wooden dolls of decreasing size placed one inside the other. The dolls often follow a theme, aside from the typical traditional peasant girls, the themes vary. Ever Played with these dolls as a child? Well I have gotten the chance to have fun with them once again, and wish that I would have kept my setfrom my childhood. They make a great shadow box.I wonder what happened to that old set of Russian Dolls I had.
