A national printer in the early twentieth century has been asked to engrave this photograph as a commemorative postage stamp. The original crop is the picture area. The person is still that person: same age, hair, clothes, and expression, translated into a dense field of burin lines rather than into a drawing of someone else.
A narrow ornamental frame in the same engraving runs around the portrait. Put a small fictional denomination in one corner and leave the country name off — no readable nation, no real coat of arms, no barcode. The paper is gummed stamp paper, slightly creamy, with a complete row of perforations on every edge. Tiny fibres show in the sheet. The ink is a single deep hue, either forest green or claret, and the white of the paper stands in for the highlights.
Photograph the stamp straight-on so it fills the frame, as a collector would shoot it on a black cloth. Not a photograph with a drawn border, not a modern vector logo, not a wax seal, and not a banknote collage.
