Restore and colorize this vintage portrait using historically accurate restoration techniques while preserving the subject's original identity, facial features, expression, pose, clothing, and composition. Remove scratches, cracks, dust, folds, stains, fading, film grain, blur, and all age-related damage without changing the person's appearance. Reconstruct missing details naturally and seamlessly, preserving authentic textures and period characteristics.

Analyze the approximate era of the photograph and apply realistic, historically accurate colors. Use natural olive skin tones, dark brown eyes, black hair, an olive-green military cap, a gray-green military coat, a white dress shirt, and a dark brown tie. Maintain realistic fabric textures, accurate lighting, and subtle shadows. Keep the background as a soft neutral studio gradient.

Enhance facial details with realistic skin texture, sharp eyes, natural lips, and clean edges while avoiding any artificial or overprocessed look. Preserve the vintage character while making the image appear professionally restored.
