Traditional Semenov dolls are a study in graphic simplicity, a folk style that has endured over the decades. Available here is the most popular size of all, the 6-piece version. Why is the six nesters so popular? Maybe it's because it matches The Littlest Matryoshka book, sold separately. Or possibly because six-piece dolls are rather rare compared to their 5-piece cousins. This is a good piece with which to introduce a favorite youngster to the joys of matryoshka collecting!
