Luxury fountain pen advertisement with ink trail

Create a premium advertising poster for a luxury fountain pen. The pen stands upright in the center of a clean ivory background. A flowing trail of black ink emerges from the nib and transforms into elegant handwritten letters, architectural sketches, signatures, poetry fragments, and creative ideas floating through the air. The transformation should visually communicate that great ideas begin with a single stroke. Use sophisticated typography, minimal luxury branding, refined editorial design, premium negative space, realistic metallic materials, soft studio lighting, subtle paper textures, and high-end commercial photography aesthetics. Headline: "WRITE WHAT LASTS." Luxury print campaign quality, simple composition, strong visual metaphor, ultra realistic, 4:5 vertical poster.
