- The New-York Historical Society's collection includes four separate sets of contact prints made from Victor Prevost's original calotype negatives. None of the sets are complete. This digital collection presents the best available print for each of the 44 negatives. The prints are undated, but those given by Samuel Hoffman's family were made prior to his donation of the negatives to N-YHS in 1906; prints made by N-YHS were made after that date.
