Introducing a vibrant and lively vertical bookmark inspired by the book cover "Death on the Douro." Measuring 2.5 inches wide and 8 inches tall, this bookmark features a stylized and harmonious illustration of the Douro River flowing gracefully through rolling hills. The landscape is filled with soft greens, warm browns, and a clear blue sky, with abstract clouds and birds adding movement and life. On the front side, the title "Death on the Douro" is displayed in a playful, bold font at the top, with a contrasting color like bright white or light blue, and a clean shadow effect to make it pop.
