The piece in the image is a surrealist architectural seascape print by American artist Eric Adolfson.
Adolfson is well known for his distinct late-20th-century vaporwave and surreal aesthetics, frequently combining clean geometric layouts, checkered floors, stark architectural openings, and vibrant pastel cloudscapes over open oceans. This specific limited edition lithograph features a pencil signature and an edition number (looks like 349/480) visible in the bottom-left corner.
