Vintage Lille Prins Rumkort

Create a vintage illustrated postcard designed as a whimsical collaboration between {argument name="franchise name" default="The Little Prince"} and {argument name="space company name" default="SPACEX"}, shown as the front and back of the postcard side by side on one canvas. Use warm aged paper with slightly worn edges, subtle grain, faint stains, and a nostalgic mid-century print feel. The left half is the postcard image: a deep midnight blue starry sky with small golden stars and a tiny ringed planet, a large white rocket standing upright on a launch pad with bright exhaust at liftoff, and a small blond child in a green outfit with a long golden scarf sitting on a rocky hill beside an orange fox, both seen from behind and looking toward the rocket. Add elegant hand-lettered quote text in the sky that reads {argument name="quote" default="To the stars, what matters is invisible."}, with smaller serif and script attribution beneath: "ANTOINE DE SAINT-EXUPÉRY" and "The Little Prince". Along the bottom of the left panel, include 2 brand names: "The Little Prince" in blue script on the left and "SPACEX" in bold blue futuristic capitals on the right, separated by a small gold star and a thin divider line. Beneath that, add the slogan in spaced small caps: {argument name="tagline" default="EXPLORING WORLDS. CARING FOR WHAT MATTERS."}. The right half is the postcard back on the same aged paper, with a centered heading "POST CARD" near the top and a small gold star ornament below it. Add a circular postmark near the upper center-right with 4 visible text parts arranged inside the stamp: "PLANET EARTH", "MAY 23", "2024", and "BEYOND". In the top-right corner, place a blue postage stamp with perforated edges showing the Little Prince standing on a tiny planet under stars, with 4 readable text elements: "1943", "Le Petit Prince", "SPACE", and a small star symbol. The right side should have 2 writing columns divided by a vertical line. In the left writing area, place a handwritten-style message beginning with "Dear friend," followed by this text in neat cursive line breaks: "One day, we'll leave Earth not to escape it, but to understand it better. The universe is vast, but kindness is our compass. Let's take care of our home, as we reach for the stars." Then sign it on 3 lines: "The Little Prince", "and", "SPACEX". In the right address area, write "To you," on the first line, then "Somewhere wonderful" and "In the Universe" on the next lines with horizontal guide lines. Add small gold star doodles and, at the bottom-right corner, a simple line drawing of a tiny round planet with little flowers sprouting from it. Keep the palette limited to cream, navy, soft gold, muted green, warm orange, and blue-gray, with crisp but painterly illustration, accurate decorative typography, and a magical, hopeful, literary-meets-space-exploration tone.
