Is the corroded copper plate painting worth collecting in the Republic of China?

It has collection value. Copper plate color painting is a new technology to fill the concave-convex texture of copper plate after corrosion. Because of the combination of sculpture and painting, the works have both a sense of hierarchy and a sense of three-dimensionality. Copper plate color painting mainly inherits the inscriptions on ancient bronzes and the patterns hand-carved on gold and silver vessels in Tang Dynasty. During the Ming and Qing Dynasties, many gold, silver and bronze utensils were engraved with characters and patterns, among which the hand-carved ink boxes and hand stoves were the most prominent. This is a miniature copper plate with landscapes, figures, flower and bird patterns and the author's calligraphy inscription. Copper plate color painting is a kind of handicraft in intangible cultural heritage, which has great collection value.
