Both images show wear inside the glass, unaware if it’s from the sealing process or from the emulsion process ( I would presume sealing). Both images are sealed using some kind of tree sap / resin, with some remnant sealing tape in place along the edges. Brass mats and preservers show light patina from age. The case is in excellent shape. Hairline cracks near the top hinge and on one side wall. Hinges a bit loose on the the lid but holding. Clasp functional.
