A powerful Basque festival poster set in Gorliz coast at night. Minimalist but emotional composition. In the lower part, a dark stylized beach and bay. In the middle, small simplified festival stands (txosnas) glowing with warm lights, arranged in a curved line. Thin glowing lines connect them, forming a network. This network rises upward and transforms into a massive ocean wave made of human silhouettes, raised arms and flags, symbolizing collective strength. Strong contrast, deep navy blue, red and warm orange tones. Bold, graphic, screen-print style, slightly vintage political poster aesthetic, grainy texture, high contrast, dramatic lighting. Minimal text: "BAT". Mehr sehen
