Ilia Murometz (panels sketch) Roerich N.K. (Part 1)

The picture has something of this: mural, wall, ancient, artistic, graffiti, antique, culture, vintage, retro, spray, design, visuals.
Perhaps it’s a painting of a man riding on the back of a white horse with a bow and arrow in his hand on top of a hill with a city in the background.
