antique photograph prop 3d model

Create a realistic 3D game-ready antique photograph prop based on the reference image. A single old rectangular photograph with both front and back surfaces, slightly curved and physically thick like real aged paper. Heavily weathered sepia photographic texture, torn corners, cracked edges, wrinkles, scratches, stains, faded areas and realistic paper fibers. Front: vintage sepia portrait of a young woman seated with a stern bearded man standing behind her. Back: aged paper with handwritten text: “You were never supposed to find this. — A” and a faded 1923 stamp. Use realistic PBR materials, roughness, normal and color textures, clean topology, UV unwrapped, optimized for real-time web/game use. No background, no frame, no extra objects. The photograph must be a single 3D asset that can be placed on a desk and rotated to inspect both sides.
