Outstanding light lit the narrow faced man who had a lengthy nose, nicely proportioned lips, and clear bright eyes. Didn’t the guy appear to be at peace with himself in this retaped sixth plate that has good contrast and nice reflected depth?

There is a brown stain above his shoulder. Tarnish stays close to the scalloped edges.
