Caral Site-Emblem T-Shirt, Peru

The stepped silhouette of Caral's Great Pyramid, 150 metres long, up to 28 metres high and radiocarbon dated to around 2627 BC, printed alongside the geometry diagram Pyramason actually tested against the site's own regional cluster, not an invented alignment. Beneath it: Caral, Peru, -10.893611, -77.520278. Those are Pyramason's own catalogued coordinates for the oldest known city in the Americas.

• Great Pyramid stepped-platform silhouette, Caral's most recognisable structure
• Geometry diagram shows Pyramason's real test result, with no invented ley-line mysticism
• Exact coordinates (-10.893611, -77.520278) printed beneath the monument and country
• Soft, pre-shrunk cotton in a minimalist gold-on-dark line-art treatment

Why this site. Caral is the oldest known city in the Americas, its age proven by radiocarbon-dating reed bags used as pyramid fill rather than by legend. Its golden-ratio test still came back consistent with chance. The honest result is printed on the shirt instead of a manufactured mystery.
