Cover of the collection of poems by K. D. Balmont The Firebird. Slavic flute Konstantin Andreevich Somov (1869-1939)

The picture has something of this: decoration, flower, retro, design, vintage, texture, antique, traditional, image, style, culture, vector, handicraft, handcraft.
Perhaps it’s a painting of a woman with a parasol in her hand and a butterfly.
