阿尔卑斯铁道旅行

A vintage travel poster in 1930s railway style advertising 'VISIT MONT AVELINE.' A stylized cog railway climbs snow-capped peaks under a graduated sky of teal to gold. Bold streamlined art-deco lettering arcs across the top; a small crest reads 'Northern Alpine Line.' Flat screen-print color separations, subtle paper aging, sharp geometric mountains. Palette of teal, cream, warm gold, deep navy. Nostalgic, elegant, golden-age-of-travel romance.
