Vintage Stamp Postcard

Generate a vertical 3:4 vintage commemorative postcard from the reference photo provided. The reference photo is the only basis for the whole composition: every person, animal, plant and object in it must be preserved exactly — the same count, the same poses, the same physical features, the same relationships to one another. Do not add a subject and do not remove one.

Split the frame into two equal halves, with the dividing line at the exact vertical centre:
The top half carries the original photograph in full, with all of its real photographic texture, cropped horizontally only as far as the frame requires. Nothing inside the photo may be altered.
The bottom half is warm, aged ivory paper. On it, distil the photo's core subject — plus one or two of its most recognisable background details — into a single round vintage commemorative stamp, centred.

The stamp keeps only the three to five most essential subjects and omits the rest. It must sit entirely within the bottom half of the frame: it may not cross the centre line and it may not overlap the photograph above.

Render the stamp strictly as a hand-carved rubber stamp crossed with an etched print: describe the scene in broken lines of uneven weight with naturally worn, ragged edges, simplifying realistic detail to a minimum while fully preserving each subject's silhouette, posture and instant recognisability. Take two or three dominant colours from the original photo and convert them into slightly faded old stamp-ink shades — brick red, ochre, turmeric yellow, olive green and deep brown are typical of old stamps. Reproduce the marks of a stamp genuinely pressed by hand: ink that varies in density, colour plates that register slightly off, and patches where the ink skipped and the bare paper shows through.

Directly beneath the stamp, draw two horizontal blank bands, centred: the upper one wider, the lower one narrower, with a gap between them. These bands are where a caption will later be written by hand, so their interiors must be clean, empty paper containing no letters, words, numerals or symbols.

The overall mood is mid-twentieth century: an old travel journal, a field notebook of nature observations, a well-franked postcard — warm and nostalgic.

Strictly forbidden: altering, adding or removing any subject from the original photo; incongruous styles such as slick modern vector art, anime, watercolour bleed, thick impasto oil paint, 3D rendering or glossy icons; a left-right split instead of a top-bottom one; and any watermark, platform play button, Chinese subtitles, QR code or heavy black border.
