This mirror dates from the 1950s and is a characteristic example of French post-war interior design. The piece has an ebonised frame, a finish in which wood is darkened to resemble ebony. This gave mirrors from that period an elegant, understated look that suited both classic and more modern interiors. The mirror surface is made of mercury glass, a technique that was mainly used before and around the middle of the 20th century. Instead of the modern silver coating, a mixture containing mercury was used, resulting in subtle ageing, a slight haze and sometimes characteristic staining. This natural patina is highly valued today and contributes to the authenticity of the object. Its origin in a Parisian bistro indicates intensive use in a public space, where mirrors were often used to reflect light and visually enlarge the space. Such mirrors were not only functional, but also an important decorative element in cafés and bistros in Paris. Based on its size, proportions and style, it is likely that this is a fireplace mirror (trumeau or mantelpiece mirror). This type of mirror was traditionally placed above the fireplace and is characterised by a rectangular shape, often with a sober but powerful frame. In bistros, this model was regularly reused as a wall mirror, separate from a fireplace, which may also have been the case with this example. In summary, this is an authentic French mirror from the 1950s, with an ebonised wooden frame and original mercury glass, originating from a Parisian bistro and probably originally designed as a fireplace mirror. A decorative and historical object with clear signs of use that contribute to its charm and value.
