Inventor's Wing Study

An open, aged parchment notebook displays detailed sepia-toned sketches of a bat-winged glider, two toothed gears, and a threaded screw mechanism. Fine cross-hatching and handwritten script in the upper left lend the page a vintage, technical aesthetic. The warm, earthy palette and dark, irregular edges frame the intricate mechanical drawings.
