Four Quiet Machines · Workshop Patina 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 black vinyl disc with printed card sleeve, a midnight blue, silver and off-white palette, and a standard twelve-inch sleeve with a circular die-cut. Recorded display dimensions are 31.5 × 31.5 × 0.7 cm. The gallery documents gentle handling wear with no structural loss; one invented geometric maker symbol; no readable lettering. 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.
