Fictional Japanese Rocket Stamp Sheet

Goal: Create a realistic fictional Japanese postage stamp sheet themed around the history of Japanese rockets, like a collectible commemorative issue. Canvas: Square image, straight-on view, showing one full perforated sheet on a neutral beige background. The sheet contains exactly 16 individual stamps arranged in a 4 columns by 4 rows grid, each stamp identical, separated by black circular perforation holes and cream paper gutters. Add a subtle paper texture, slightly aged off-white edges, and a printed lithograph feel. Stamp design: Each of the 16 stamps is a vertical rectangle with a cream border and dark ink outline. Inside every stamp, depict a dramatic vintage space illustration: multiple Japanese rockets launching and standing upright in chronological progression, smoke clouds and orange launch glow at the bottom, a dark navy starry sky above, orbital arcs, a small satellite near the upper left, and small black date/name labels near the rockets. Use a nostalgic 1950s–1970s science poster style with muted navy, cream, sepia, gold, white, black, and warm orange tones. Text content: On the left side of every stamp, include a vertical Japanese title reading {vertical_title_text}. Along the bottom border of every stamp, include the denomination {stamp_denomination}, then {country_name}, then Japanese postal text {postal_text}. Make the text small but visibly printed, with slight imperfections like real stamp ink. Subject details: Include exactly six main rockets on each stamp, from a small early rocket at the lower left to taller white and gold launch vehicles toward the right. Add exactly one satellite illustration near the upper left of each stamp. Add several tiny black annotation plaques with years and rocket names, but keep them decorative and not overly readable. Visual style: Highly detailed generated illustration, vintage Japanese commemorative stamp aesthetics, crisp perforations, warm aged paper, fine engraved linework, realistic printed texture, symmetrical sheet layout, museum-collector presentation. Constraints: Show exactly 16 stamps, no extra stamps cut off at the edges, no modern logos, no watermark, no people, no photorealistic rockets outside the illustrated stamp artwork.
