The artwork is a four-panel piece featuring a scene of elegantly dressed riders on horseback. It is a reproduction of a famous painting called Court Beauties on an Outing (丽人行图), originally attributed to the Song Dynasty artist Li Gonglin (Style Name of Zhang Xuan) (1049–1106).
After a few months of research finally found it's origin:
This painting is based on a poem from the poet Du Fu during the Tang dynasty. Satirically describing an extravagant spring outing by the sisters of the imperial consort Yang Guifei. The painting itself is a 12th-century copy of an earlier 8th-century work by the Tang Dynasty originally composed by the artist Zhang Xuan!
