Create a vertical 9:16 vintage propaganda-poster-style promotional ad for a generic AI image service. Use a bold red-and-yellow radial burst background, aged paper texture, heavy retro Chinese headline typography, and an exquisite retro illustration of a smiling, elegant, approachable young woman in the center. The poster should feature prominent Chinese promotional text about a latest AI drawing service, an amazing price of 9.9 per image, suitable use across many scenarios, image blending, partial repainting, three revisions per submission, and direct AI output that is ready to use. At the bottom, include a clear call to action meaning: if interested, click the "I want it" button at the lower right, with a drawn finger-clicking gesture near the button. Use a fictional or generic AI service mark at the lower left instead of any real company logo. Keep the design energetic, nostalgic, readable, and commercially polished. Avoid real company names, copied logos, official-looking OpenAI marks, guaranteed results, misleading service claims, private information, extra watermarks, unreadable Chinese text, distorted faces or hands, cropped key text, and low-resolution artifacts.
