Curtain 

"Curtain" by Boris Kustodiev is a vibrant and playful depiction of a theatrical stage. The red velvet curtain is drawn back, revealing a glimpse of a bustling city scene. The rich, stylized floral patterns on the curtain, typical of Russian folk art, contrast with the bright colors and simplified figures. The playful humor of the scene is emphasized by the figures in the foreground, creating a lively snapshot of Russian entertainment. The image is characteristic of Kustodiev's "Russian" style, which emphasized the unique cultural identity of his native country.
