Hello, this item is a pair of large Chinese carved wooden shop or architectural signboards, most likely dating to the late Qing dynasty through the Republican period, approximately late 19th to early 20th century rather than 400 years old. The elongated format, deeply carved gilt characters on a black lacquered ground, and surviving suspension loops are characteristic of commercial or ceremonial signboards once displayed outside shops, guild halls, temples, or traditional residences. The red and gold calligraphy reflects auspicious and prosperous symbolism common in southern Chinese decorative traditions. The smaller seal-style cartouches likely contain workshop or studio marks, blessings, or poetic inscriptions. The heavy weathering, oxidized surface, layered paint remnants, and erosion appear consistent with prolonged exposure and genuine age rather than modern decorative reproduction. Their impressive scale also adds significantly to their decorative and collector appeal.

Condition shows extensive surface wear, paint and gilding loss, oxidation, cracking, and environmental deterioration throughout, but this aged appearance contributes to the authenticity and visual character of the pieces. Because the inscriptions have not been fully translated and provenance is limited, attribution to a specific region or institution remains uncertain. However, large original Chinese architectural signboards have become increasingly desirable in the Asian decorative arts and interior design market, particularly for collectors interested in vernacular architectural elements. Based on comparable sales for authentic late Qing and early Republican period carved signboards of similar size and condition, the fair market value for the pair would likely range between $2,500 and $5,500 USD.
