Vintage Teddy Bear Storybook Illustration

"Create a detailed vintage storybook-style illustration of an anthropomorphic teddy bear standing upright, wearing a blue and cream varsity letterman jacket, a matching blue cap, and cream trousers with sneakers. The bear holds a wooden bat propped over one shoulder in one paw and waves a small triangular pennant flag in the other paw with blank space for custom city text. Soft painterly linework, warm sepia and cream tones, elegant heritage-brand illustration style reminiscent of classic children's book art. Centered, isolated on a plain cream background, no additional text baked in."
