Art Deco 1920s Luxury Poster

Restyle the source image as a 1925 to 1935 French Art Deco luxury travel poster in the manner of A. M. Cassandre (Normandie, Étoile du Nord, Dubonnet), Paul Colin, and Jean Carlu. Render as a five to seven color stone lithograph on heavy poster paper. Palette: deep navy and ultramarine, ivory cream paper ground, brick red, ochre gold, jet black, soft warm grey, one accent of metallic copper or silver. Forms are geometrically simplified into planes and arcs, machine-age stylization with no rendered detail, no shading gradients, only flat color shapes separated by clean drawn contour. Compositions exaggerate scale: a single object (ship's bow, locomotive nose, glass) rendered monumental from low-angle perspective, dwarfing any human figure. Diagonal thrust lines, perspective vanishing dramatically. Skies are flat gradient bands. Smoke, steam, and light rays are rendered as geometric solids, not atmospheric effects. Include vertical or horizontal text zones in the negative space (typically a sidebar or banner) for poster title and route copy, but render these zones empty: no letterforms, no kerned type, no script, no railway emblems, no shipping line logos, no airline crests. Preserve the exact subjects, faces, poses, gestures, and spatial arrangement of the source image without alteration; restyle the rendering only.
