The State Street Bank and Trust Company of Boston has one of the most important collections of New England maritime arts in the United States. However, no program had been established for the conservation of these objects until 1973, the first step being an inventory file. This initial survey found almost all of the ship models dirty and deteriorating from atmospheric pollution. Restoration was entrusted to a ship modelmaker whose guiding policy was that these models were to be treated as folk art. The bank contracts work to specialty conservators for paintings, paper items, and wood objects. Several projects are briefly reviewed; the care provided for the prints had caused the most problems because storage had been under acid conditions. The conservation philosophy followed is conservative in its approach to protecting the historical integrity of its artifacts. The restoration file is kept with the catalog record. Display of the objects as part of the furnishings of the bank has required a great deal of planning of the placement of the objects, for each work must be set in an environment which is the least damaging. Regular cleaning of the objects is performed by the curatorial staff, not the contracted maintenance service which is responsible for the buildings.
