Cover of the theater program of the Theater de L Hermitage. January 21 Konstantin Andreevich Somov (1869-1939)

The picture has something of this: antique, baroque, picture frame, ornate, victorian, retro, vintage, decoration, Renaissance, ancient, margin, engraving, classic, text.
Perhaps it’s a drawing of a picture frame with the words theatre and a picture of a horse in the middle of the frame.
