Vintage stamp of naive folk art illustration on a postage stamp, bold black outlines, stippled dotted shading technique, cream off-white paper background, perforated serrated stamp edges, slightly aged paper texture, hand-drawn feel, limited 2-3 color palette, small decorative elements, square format. CRITICAL: zoom in close, the stamp subject fills 95% of the canvas edge-to-edge, extremely tight crop with near-zero white space, stamp fills the entire image, NO padding outside stamp edges, NO background frame, ONLY the stamp visible, zero margin. ABSOLUTELY NO text, NO words, NO letters, NO numbers, NO writing, NO typography, NO labels, NO captions — the image must be purely illustrative with zero readable characters, blue-grey and cream color palette, delicate floral accents, stippled blue background. Subject: a decorative design. Use input_image_0 as the structural reference; preserve the recognizable silhouette, proportions, geometry, negative space, and major shapes while converting it into a stamp illustration. No text, no words, no letters, no numbers, no writing, no typography, no labels — purely illustrative.
