A formal portrait engraving by Christophe Guérin depicting Adrien de Lezay-Marnesia, the Prefect of the Bas-Rhin, in his official uniform.

This portrait engraving by Christophe Guérin depicts Adrien de Lezay-Marnesia, the French administrator who served as the Prefect of the Bas-Rhin department. Guérin, a skilled engraver based in Strasbourg, captures the subject in a formal bust-length pose, framed within an oval. The work reflects the precise, disciplined aesthetic of early nineteenth-century French printmaking.

Lezay-Marnesia is shown wearing his official uniform, which features detailed embroidery of oak leaves along the collar and lapels. The artist employs fine cross-hatching and varied line weights to render the texture of the fabric and the metallic sheen of the medals pinned to the chest. The subject's expression is composed, conveying the gravity associated with his administrative role during the Napoleonic era.

Below the portrait, the engraving includes formal lettering identifying the subject and his title, alongside a note regarding his death in Strasbourg in 1814. This inclusion of text is characteristic of commemorative portrait prints from the period, which functioned as both personal records and public documentation of figures in authority. Guérin's technique demonstrates a high level of control, particularly in the modelling of the face and the subtle shading that gives the figure a sense of volume. The composition remains balanced, adhering to the conventions of Neoclassical portraiture where clarity and order take precedence. This print provides a clear view into the visual culture of the French administration, where portraiture served to codify the status and identity of public officials. The work remains a representative example of the technical proficiency found in the Strasbourg school of engraving during the early nineteenth century.
