Treatment of damage at the edges
Detail of the lower edge of the painting, showing brown paper plus wood and gesso from the frame embedded in the paint
Along the edges there are areas where brown paper has been left in place. This appears to have been left over from the first lining. Over the brown paper in places there is gesso which appears to have come from the frame. This is evident around most of the edge and must have become attached to the paint layer or brown paper before the second lining.
The gesso is now embedded in the paint layer, and removal of the gesso leaves a depression where the gesso had been pushed into the paint. The gesso was thinned with a scalpel down to the original paint layer. It was decided that the gesso would not be removed as it would leave a loss that would necessitate filling.
