登山鉄道 · 70年代の暖色

Retro vintage poster artwork of a little red cog railway train climbing a steep mountainside, in a 1970s screen-print style with orange, brown and mustard tones and wavy lines. Bold simplified shapes, a limited color palette, halftone texture and aged paper grain, strong graphic composition. Purely visual: no text, no lettering, no numbers, no logos. Vertical 4:5.
