Sometimes assumed by Westerners as "medical models" these are Chinese fertility dolls. As ritual items, they rarely come onto the market. Used by several Chinese ethnic minority cultures, including the Miao, Yao and Naxi, the old fertility dolls were hand carved, anatomically correct and with pegged and jointed limbs. The hair styles and head gear would vary depending on the minority group. Dolls representing the hopeful parents to be and often the son that was wished for were consecrated by the shaman and taken home from the temple. After a child was born, the child doll would be returned to the temple.
This pair is in tact and good condition, with some paint loss. Approximately 150 years old. Each doll is approximately 37 cm tall, 10 cm wide at the shoulders and 6-7 cm thick. 14+ inches x 4 inches x 3 inches.
