Sepia Gear Aeronautics

An open, aged notebook spread displays sepia-toned ink drawings of a central flying machine featuring a propeller, exposed gears, and wing struts. Smaller sketches of bat-winged contraptions and side-profile views surround the main subject, accompanied by blocks of illegible handwritten script. The warm, monochromatic palette and fine cross-hatching evoke a vintage technical study, ideal for a dark desktop background.
