On Friday February 2, 2018, when I opened The Wall Street Journal to the second page, I saw a photograph of Rhona McBeth at the Museum of Fine Arts Boston looking into a microscope as she examined a Rembrandt painting (“Great Artwork Gets Careful Cleaning at the Museum”). There was no article; only a caption that noted that, over the next year, paintings will be cleaned at the museum in the view of visitors. To find information (however little) about conservation in such a prominent location is a good thing.
