A 1940s-era travel poster in the spirit of mid-century European railway lithographs, vertical 24x36 inch format, advertising a fictional alpine lake destination. The composition uses a high horizon line with a turquoise glacial lake in the foreground, a wooden rowboat with a single figure in a red sweater drifting on calm water, and a dramatic stylised mountain range with snow-capped peaks rising behind. The sky is a flat gradient from pale apricot at the horizon to deep cobalt at the top, dotted with three stylised cirrus clouds painted as simple white brushstrokes. Foreground pines are reduced to flat dark green silhouettes with crisp angular edges. The palette is muted and limited: ochre, sage, cobalt, ivory, brick red. Texture has a subtle paper grain and slight registration offset as if printed in four stone-lithograph passes. Bold sans-serif headline at the top reads "DISCOVER LAKE FENWICK" in chunky condensed letters, and a smaller line at the bottom reads "RAIL & FERRY TICKETS FROM EVERY STATION". A small badge in the lower right reads "1947".
