A vintage winter-sports travel poster for the invented resort 'GLACIER PLATEAU.' A stylized skier carves down a bright white slope under crisp blue skies and geometric snowy peaks, a plume of powder trailing behind. Bold condensed deco caps arc across the top; a small crest reads 'winter season.' Flat lithograph blocks, subtle grain. Palette of ice blue, crimson, white, warm cream. Crisp, energetic, alpine mid-century glamour.
