The National Gallery of Art knows a thing or two about preservation. In addition to the many works on view in its public galleries, countless others are tucked away at its conservation division in Landover. For those curious about the conservation progress, the NGA is mounting a new show drawn from the book collection of noted conservation scientist Robert L. Feller. In addition to his volumes exploring the science of color and history of paint, visitors can see Feller’s journals from his 1966 trip to Florence, Italy, where he worked with conservators responding to the city’s flood.
