Harbor Signals 7-inch · Archive Blue is a curated recorded-music item prepared for the Collectorium T launch selection. The package translates the recording's quiet, nocturnal character into material choices that reward handling and close viewing.

Its visual identity combines translucent vinyl and die-cut paper jacket, a vermilion, charcoal and kraft paper palette, and a compact seven-inch sleeve with folded seams. Recorded display dimensions are 31.5 × 31.5 × 0.6 cm. The gallery documents honest age-consistent wear, photographed without cosmetic concealment; small non-legible inventory glyph and age-consistent handling marks. Each image is a separately composed camera view of the same presentation piece. This presentation record is informational only; ownership, maker attribution, certification, scarcity and provenance verification are outside its scope.
