Stone Signal Deck · Small Horizon is a curated card collection prepared for the Collectorium T launch selection. The series was designed as a complete visual index rather than a single hero card; sequence and consistency are central to the set.

Its visual identity combines matte coated cards with rounded corners, a forest green, coral and cream palette, and a small series in individual sleeves. Recorded display dimensions are 54-card deck; 8.9 × 6.2 cm each. The gallery documents honest age-consistent wear, photographed without cosmetic concealment; unmarked surface with hand-finished tool traces. 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.
