A modern, corporate-style A2 poster for a mountain club, designed using a 7:10 grid layout. The background features a geometric pattern inspired by mountains, using minimalist triangles or topographic lines instead of gradients to ensure a clean print result. The color scheme consists of navy blue, baby blue, and yellow for a strong visual contrast. The poster includes four horizontal photographs arranged dynamically in different shapes—some as rectangles, others cut into mountain silhouettes. Each photo has a white or thin black border for clarity. Additional graphic elements include simple swooshes, circular arrows highlighting key information, and stylized mountain shapes to reinforce the theme. Typography is bold and clear, avoiding gradients. The main headline is highlighted in a strong, contrasting color (such as yellow on a navy blue background). The fonts are sourced from Adobe Fonts, with "Acumin Pro" for the main content and "Manuka" or "Alverata" for the headings. The club’s round logo is placed prominently in the upper section. Key text highlights (maximum 6 headlines) are arranged in different font sizes to create a sense of dynamism and engagement. The messaging encourages users to join the club, take on the challenge of conquering Poland’s mountain crown, and participate in exclusive competitions for the most active members. The design is fully optimized for office printing, ensuring all elements remain sharp and legible while managing ink efficiency. The top and bottom margins have been increased for better balance and readability, ensuring a professional and polished layout.
