Create a striking vertical 9:16 Spring 2026 city poster for Boston with an elegant celebratory mood and bold contemporary graphic design. Use a clean off-white textured background with large areas of refined negative space. In the lower right corner, place a miniature single sculler rowing across a narrow ribbon of reflective water. Let the oar wake sweep upward in a dynamic calligraphic curve, gradually transforming into the Charles River and then into a dreamlike hand-painted Boston panorama. Inside this flowing river-shaped composition, include recognizable Boston elements: the Back Bay skyline, Beacon Hill brownstones, Acorn Street, Boston Public Garden, Swan Boats, the Zakim Bridge, Fenway-inspired details, historic brick architecture, harbor ferries, and the city's waterfront atmosphere. Add soft morning fog, golden spring light, subtle crimson and gold celebratory accents, rich detail, layered depth, and a sophisticated city-poster aesthetic that feels fresh, refined, visually powerful, and not overcrowded. In the lower left, set elegant, clearly composed typography reading "SPRING 2026" with the vertical slogan "BOSTON, A CITY OF RIVER, MEMORY, AND INVENTION". Keep the text clean, legible, and beautifully integrated into the premium graphic design.
