Self-publishing book cover design for: "Contra Portada". Genre: business / non-fiction, minimalist symbolic cover archetype, serious academic mood, high-contrast monochrome palette; create a photorealistic print-ready 5:8 portrait composition focused on the back-cover concept, with a clean modern book shown from a slight rear three-quarter angle so the contra portada is clearly visible, featuring refined placeholder blocks for synopsis text, barcode area, and publisher mark area using elegant matching typography. Polished publisher-quality design with title and author placeholder text rendered cleanly, studio lighting, premium paper texture, no real logos, no watermarks.
