ENGRAVING PIEDRA DE PERTUIS. JURA. SWITZERLAND.

Description:
- Engraving Piedra de Pertuis.
- The stone of Pertuis, also called the perforated rock or Roman tunnel of col de Pierre Pertuis, tenderne a passage of Roman road inlaid in the rock, creating a door similar to the Besançon.
- All the titles and signatures are outside the plate. The draughtsman is unknown.
- In the upper margin is the legend 'Jura - Jura'.
- In the lower margin is the legend 'Pierre Pertuis - Piedra de Pertuis - Pertuis Felsen'.
- In the upper right-hand corner is printed the number '2', which suggests that the engraving is number 2 of a series.
- In the lower right corner, the Engraver signs only as Rouargue, so it is by one of the two Rouargue brothers. In our opinion, the author of the engraving plate is most probably Adolphe Rouargue (1810 - 1870).
- Chalcographic etching on steel plate, although another technique could also have been used.
- It is in single-colour black tone, very well inked.
- It is probably an engraving belonging to a book.
Conservation and damage:
- General condition: Fair.
- The upper side of the paper is not parallel to its opposite side, resulting in an irregularly shaped engraving.
- The engraving has a thin paper of regular quality.
- It is very well inked, and has a good stamping.
- The upper margin is thin and irregular and the lower margin is thin. The side margins are wide.
- The engraving has suffered from humidity, so the paper has damp stains and rust spots, all of which are more pronounced as we get closer to the edges.
- The engraving is dirty, and the edges are much dirtier, with very small tears, and the tips are slightly deteriorated with slight bending.
- A light washing and bleaching would be a very good result.

Comments:

- Ideal engraving as a decorative element.
- The tones of the colours in the photos are not the same as the tones of the real colours.
- The Engraving for sale is the one that corresponds to the photos. The description is not a detailed exposition of it.
