A calligraphy brush made by Yanglin Calligraphy and Painting Company, approximately 20cm in length. I found this while cleaning out my grandfather's house. I'm not sure if it was ever used. "This is a traditional Tang brush (Chinese brush), likely a calligraphy and painting brush named 'Xuefeng'. Inscription: The characters '雪峰' (Xuefeng) and '揚州書画社' (Yangzhou Calligraphy and Painting Company) are visible on the shaft. Usage: It is believed to be a type of large brush used for calligraphy and ink painting. Size: There is an engraving of '四號' (No. 4), which indicates the size of the brush. Hair Quality: Based on the color of the bristles, it could be a pure sheep's wool brush (jun yang hao), or a mixed-hair brush (jian hao bi) possibly blended with horsehair." I am not knowledgeable about this, so I used AI to get the information above. - Brand: Yanglin Calligraphy and Painting Company - Size: Approximately 20cm - Material: Brush Thank you for looking.
