Resonance Engine Music Box Poster - Fictional Sound Machine

Resonance Engine music box poster presents a fictional hand-cranked acoustic instrument as a detailed technical illustration. A flared horn rises above an exposed pinned cylinder and comb, while the crank, auxiliary views and labeled details complete the layout. Fine blue-gray drafting lines and crosshatching shape the mechanism against a pale ground, with restrained copper accents on the horn rim and crank. The title and small labels give the composition its technical-plate character. Physical, unframed print in A5, A4 or A3. Frames and styling accessories shown in mockups are not included.
