What periods do these wall plaques come from?

The pieces span from the eighteenth century through the Victorian and Edwardian eras up to the 1930s. Grand Tour souvenirs and classical portraits often date to the earlier nineteenth century. Later items include vintage commercial signs and interwar ceramic tiles. Each period utilises distinct materials such as Welsh slate, vitriolite glass and red lacquer.

How should I clean glass and lacquered frames?

Dust surfaces gently with a soft, dry cloth to prevent scratching delicate lacquer or mother-of-pearl inlay. Avoid chemical sprays and excessive moisture on old wood and painted areas. Glass panels can be wiped with a damp cloth, taking care not to let liquid seep beneath the edge of the frame. Preserving the original finish requires minimal intervention.

Are these signs and plaques waterproof for outdoor use?

Most of these antique and vintage pieces are intended for indoor display, particularly items featuring delicate paper, ivory, micromosaic or fabric elements. Exposure to outdoor moisture and temperature changes can damage the materials. Enamel advertising signs and vitriolite glass possess greater resilience, but older frames and metal fixings remain vulnerable to weathering. Indoor placement ensures the longevity of both frame and artwork.
