A single comic-book onomatopoeia panel in Roy Lichtenstein pop art style, flat silk-screen print look, zero gradients, zero photographic realism. The sound word "Hummmmmm..." is hand-lettered in thick brush-traced comic letterforms: capital H followed by a long stretched run of lowercase-looking rounded letters, with the elongated "mmmmmm" drawn as a wavy line of connected arches that undulates gently up and down like a sustained vibrating note, ending in three round dots "...". Medium size: the word fills about 60% of the panel width, set slightly rising on a gentle 5-degree upward tilt, centred, with generous margin around it. Letters are solid flat white with a thick, perfectly uniform black outline around every contour, slight ink build-up where strokes meet, and a hard solid black drop shadow offset 45° to the lower right. Behind the word sits a small, soft-edged-free jagged-free rounded burst: a wide flat yellow oval cloud with a thick black outline and scalloped edge, sized only a little larger than the word, with three short black curved vibration lines on each side suggesting a humming sound. Panel background: flat blue filled with large, evenly spaced, individually visible Ben-Day halftone dots in a lighter flat blue on a precise 45° offset grid. A bold black rectangular comic panel border frames the whole image with a thin white inner margin. Colours strictly flat: primary blue, primary yellow, white, black, with one small flat red accent stripe along the bottom edge of the burst shadow. Crisp hard edges everywhere, vintage offset-printed comic energy, white lettering reads at maximum contrast against the yellow burst and black outline.
