This appears to be a Japanese kakejiku hanging scroll painted on silk, similar to traditional Nihonga style floral works.
The painting features prominent white peonies, which in East Asian art often symbolize wealth, beauty, and auspiciousness.
Similar scrolls featuring floral arrangements or peonies have been valued in estate sales and auctions for approximately $125 to over $260.
The piece likely includes a vertical calligraphy inscription in the upper left corner and a red artist seal.
