Virtually no additional lifting from the glass. On the edges where it had loosened a bit, the emulsion is gone. Meg served in the State Legislature for a while - this print hung on the wall behind her desk. Her comment was that she had many good memories of seeing that image on entering her office in the mornings, and that she probably has a photo of herself at her desk with this shot in the background. So even if I can’t find the negative to scan and reprint, the image will live on.
