The collection includes the pictures found and acquired by researchers and coordinated by V. Castronovo as part of the “Biellesi nel mondo” project promoted by the Gruppo Banca Sella begun in the 1980’s. By means of records, images, letters and diaries the researchers were able to piece together the history of Biellese emigration around the world between the second half of the 1800’s and the first half of the 1900’s. The photographic collection is a visual representation of this period of history. Today every exposure is kept in an envelope together with a card on which many descendants of the emigrants recorded their personal memories.
