Railway Signal Lantern Poster - Exploded Technical Study

Railway signal lantern poster presents a detailed exploded-view illustration of a railway-style lantern and its separated components. A small assembled lantern appears in the upper-right corner as a visual reference. The central mechanism is arranged diagonally on a warm-white ground within a thin double-line border. Fine black and deep-sepia technical marks, stippled shadows, and restrained red-orange accents give the study an archival, meticulous character. Physical, unframed print in A5, A4 or A3. Frames and styling accessories shown in mockups are not included.
