A black ink trumpet sweeps diagonally across a white background, its flared bell opening wide and a curling swoosh trailing beneath the valves. Bold concentric square frames with dark centers disguise two of the finder squares, while a boxy bell mouthpiece section hides the third. The brass tubing, valves and splatter dots carry the modules, with fine hatching shading the bell. Pure black on white keeps the pattern crisp, and thin speed lines add motion without crowding the data.
