A highly detailed, sepia-toned ink drawing of a platypus on aged parchment. The platypus is depicted in profile, showing its beaver-like tail, webbed feet, and distinctive duck-like bill. The illustration uses fine linework, stippling, and cross-hatching in the style of vintage scientific or natural history drawings. The background is softly textured like antique paper, with no color other than sepia ink tones. The image should match the same style, tone, and dimensions as classical anatomical ink plates. See more
