An original image that takes its structure from Barcode & QR (Style, 1974 / 1994–) and its accent from Player Piano Roll (Style, 1896–1930s). Structural cues: Stripes coding by width; Three corner finder patterns; Error-correction redundancy; Pattern made for machines. Accent cues, used sparingly: Rows of perforations; The scrolling roll; Machine-readable music; Performance physically recorded. Composition: A clear quiet zone on all four sides, away from folds and curves. Type and lettering: Module size derived from the printing condition, with a hard minimum. Let one material quality come from the second style: Paper moves with humidity, so leave reading tolerance between holes. Mood: Technology, Trust, Play, Nostalgia. Color: build on #e9e6dd, #67635d, #171615 with a single accent drawn from #e9e6dd, #67635d, #171615. Constraints: do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work. Produce an original composition in the general period languages described above.

# Cautions carried from each entry
# - Barcode & QR: Art laid over the code spends the error correction budget, and it stops scanning in a dim shop or at an angle.
# - Player Piano Roll: Punching every fine note thins the paper bridges until they tear, and the performance breaks down partway through the roll.
