During the ongoing conservation of the Museum's newly acquired Jabach portrait, Michael Gallagher and George Bisacca—assisted by Charlotte Hale, Jonathan Graindorge Lamour, Alan Miller, and Cynthia Moyer—roll the painting, which is lying on its face, onto a large cardboard tube in order to turn it over. First, the cardboard tube is lifted onto the reverse of the painting, and the top strip-lining is temporarily stapled to the tube. Next, the painting is slowly rolled onto the tube, and then carried back across the platform table. Finally, the bottom strip-lining is temporarily attached to the platform, and the painting is unrolled.
