It is such a tradition for tourists to get a set of matryoshka dolls. They come in every design, even NFL football players and the Simpsons. But not many are high quality painting worthy of high prices.
It is the law of supply and demand. Just lower the price and they will sell.
There is a high end fine art doll just like lacquer boxes, and a low end. I hope the simple ones become more affordable, I'd like some myself!
