Steampunk Height Chart Storybook Poster

A nostalgic vertical height-difference character poster in a warm steampunk anime storybook style, featuring an enormous gentle robot and a small child standing beside a central height measuring ruler. Composition & Layout: Vertical portrait poster, aged parchment texture with a pale blue-green background, sepia edge stains, a thin decorative brown border, and slightly worn corners. Down the exact center runs a vertical height ruler marked from 0 cm at the bottom to 250 cm at the top, with centimeter tick marks labeled every 10 cm. At the top center of the ruler rests a small vintage label plaque reading 「身長計」. Characters: - Left character: [a 250 cm antique brass steampunk robot named クロノ], bulky yet gentle, built from riveted brass plates, visible gears, pipes, pressure gauges, clock faces, round glass lenses, a large wind-up key on its back, and a small smokestack emitting a soft puff of steam. It bends down warmly toward the child. - Right character: [a 110 cm little girl named メイ], cute anime storybook style, dressed in rolled dark green overalls, a cream striped long-sleeve shirt, brown shoes, and an orange ribbon tying a side ponytail. She reaches upward so their fingers touch near the 110 cm mark.
