A pigeon sits on a sloped rooftop with a skyline of towers and spires rising behind it, all in black ink on white. The bird's dark wing and body patches merge with the code's modules, and the solid squares with white centers that mark the finder patterns sit behind the bird and the skyline. Thick black shapes against clean white paper keep the pattern sharp, while fine hatching on the buildings and roof planks stays light. A few scattered seeds and a small smoking lantern near the pigeon's feet add a quiet urban detail.
