The library recently earned $210,000 by auctioning a Native American doll from its collection. The carved wooden doll, from the Pacific Northwest Haida tribe, was sold by Sotheby’s auction house on May 16. The doll had been donated to the library in 1923 by Sarah Ann Nichols, a Woburn native who died in 1925 at the age of 95. Her grandfather, Captain William Martin, brought the doll from Puget Sound during a trading voyage to China in 1828. A portion of the proceeds from the sale will be benefit the library’s Glennon Archives, and the remainder will be added to the fund the library has established to support its building project.
