Argentine Shawl Maidens. The shawl maidens matryoshka from Argentina were made in very small quantities, thus are scarce. We've seen only two (this is one, the other is sold). And as an interesting variation, the first doll in the set is dark-skinned. 3 nest, 3" down to 1½".
This nesting doll has an unusual history. An enterprising group of Russians, displaced by World War II, settled in Argentina after the war. One family, keepers of the flame at the time, created a modest workshop and began making a limited number of handicrafts, including matryoshkas consisting of 4, 5, 6, 7 and 8 pieces. These sets were like miniature jewels, made from indigenous birch-like wood and nicely decorated and painted. As quickly as these dolls came to the marketplace, they disappeared.
