A vintage book cleverly transformed into a Christmas tree design. The book is positioned with pages spread open and stacked in descending size order to form a perfect Christmas tree shape, with the book's spine serving as the tree trunk at the bottom. Retro vector art style with clean, bold lines and flat color blocking. Classic vintage color scheme featuring deep evergreen, rich crimson red, antique cream, and warm golden yellow tones. The book cover features ornate vintage typography and decorative flourishes typical of old library books. Each layer of fanned pages creates distinct horizontal tiers mimicking Christmas tree branches. Nostalgic 1950s-1960s illustration aesthetic with simplified shapes and strong graphic appeal. Symmetrical centered layout with the tree perfectly balanced. Charming literary Christmas theme that merges book-lover culture with holiday spirit. | PODspy AI Design
