Elysium. Set design for the opera by K.V. Gluck Orpheus and Eurydice Alexander Golovin (1863-1930)

The picture has something of this: paper, antique, retro, vintage, ancient, picture frame, artistic, watercolor, abstract, dirty, parchment, texture, brush.
Perhaps it’s a painting of a landscape with trees in the background and a sky in the middle of the picture with clouds in the sky.
