Professional book cover design for "PASATIEMPOS para Personas MAYORES". Premium vintage editorial aesthetic on a textured off-white paper background. TOP SECTION: A massive, dominant dark navy blue banner with realistic torn, deckled edges. Inside the banner, the text "PASATIEMPOS" and "MAYORES" are in huge, bold, cream-colored typography, with "para Personas" in a medium-sized font between them. CENTRAL FOCAL POINT: A single, large, and vibrant illustration of a brain made of colorful puzzle pieces. This is the primary visual element after the title, placed prominently in the center with high detail and sharp colors. BACKGROUND ELEMENTS (SUBTLE SECONDARY PLANE): To provide thematic texture, include faint, ghosted representations of logic games in the background. Specifically: ONE single snippet of a Sudoku grid, ONE subtle section of a Word Search (Sopa de letras), and ONE small logical pattern diagram. These must be low-contrast, appearing like light pencil sketches or watermarks on the paper to ensure they don't distract from the central brain. ONE hanging tag on the side reads "200 JUEGOS". BOTTOM SECTION: Two distinct, professional circular black stamp badges: one says "LETRA GRANDE" and the other says "INCLUYE 2 BONUS". At the very base, the subtitle "Estimulación Cognitiva para mantener la mente activa" in a clean, premium serif font. Strictly no duplicate objects, zero clutter, professional graphic design, 8k resolution, clean composition
