Volume 19.1

On the Cover
Front cover: Detail of a French lithograph, Woman with Prayer Book, showing pronounced mold growth on the print's surface. Although this work—part of the collection of the Shelburne Museum in Vermont—was stored in a climate-controlled area, the tempered air was not properly circulated. During the summer months, the room's relative humidity reached levels high enough to support mold growth. Following the hiring of a conservator by the museum in 1982, the storage conditions of this and other paper artifacts were modified, and visible mold was removed from this particular print.
