Affiche rétro japonaise de toise grand-père et petite-fille

A nostalgic Japanese illustrated height-comparison poster titled "[祖父と孫娘]", featuring exactly two characters standing in profile facing each other across a central measuring ruler. On the left stands an elderly grandfather labeled "[昭夫]", height 170 cm, wearing a muted brown traditional kimono with an obi belt, tabi socks, and sandals, slightly stooped with hands clasped behind his back, gray swept-back hair, and a gentle calm expression; a dotted horizontal guide line extends from his head to the 170 cm mark on the central ruler. On the right stands a little granddaughter labeled "[結衣]", height 80 cm, wearing a soft pink smock dress over a cream skirt, pink shoes, and a dark brown ponytail tied with a red bow, looking up at him with hands behind her back; a dotted horizontal guide line reaches the 80 cm mark. Between them is a tall central height measuring scale from 0 cm to 200 cm with black tick marks every 10 cm, emphasizing 0 cm, 80 cm, and 170 cm in reddish-brown. At the top are two parchment ribbon banners reading 「おじいちゃん」 on the left and 「お孫さん」 on the right, above two ornate cream info cards displaying 「名前: [昭夫]」「身長: 170cm」 on the left and 「名前: [結衣]」「身長: 80cm」 on the right. Above the granddaughter floats a rounded speech cloud reading "[おじいちゃん、おおきいなぁ！]". Decorative details include a leafy potted plant on a wooden stool at the bottom left, a small flowering plant in a wooden box at the bottom right, and scattered falling autumn leaves. Style: vintage Japanese children's picture book and family record, sepia ink linework, warm watercolor washes, subtle paper grain, pale blue-green aged paper background, and delicate corner border ornaments.
