復古油印風飛機翱翔於河流與群山之上

A vintage-style linocut print of a biplane soaring upwards into fluffy clouds. Below, an endless expanse of green grassland is bisected by a winding blue river. In the distance, a tall, snow-capped mountain stands under a clear sky. High contrast, bold outlines, limited color palette, textured artwork, retro aviation poster style.
