The Dreamer (Le Songeur), 1854, NG Washington Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: tree, sepia, nature, landscape, vintage, people, texture, park, retro, page, paper, dawn, ancient, wood, soil.
Perhaps it’s a drawing of a man sitting under a tree next to a body of water with a bird perched on the branch of a tree in the foreground.
