The sky has been tinted a uniform shade of pale blue. On one of the prints a circle has been cut out of the backing paper behind the rose window in the façade, and two lines of pin pricks have been made, one along the base of the towers and one along the top. Red ink has been added (rather crudely) behind the top row of pin pricks and blue ink behind the bottom row.

The embossed scroll at the centre bottom of the mount identifies the photographer as 'B.K.' of Paris.

The internet isn't perhaps the best possible medium for displaying tissue stereoviews, and I would draw your attention once again to my guarantee that no sales are final, and should you decide on arrival that you simply do not like your purchase, you will receive a refund of the price of the photograph.
