Pale warm limestone — classical Roman inscription quality. Letter faces show fine calcite grain; deep V-cut serifs and hairline junctions executed with mallet-and-chisel precision. Warm ivory patina across the face; fresh cut sections reveal lighter stone beneath. Carving depth 3–5mm, architecturally precise. Gallery raking sidelight from upper-left at 20°. When no specific material is defined by the font: default to pale warm limestone — cool white specular on cut edges, warm cream-ivory on aged face, dark warm museum-gallery background. 'CHARLES / STREET' in classical Roman-proportioned letterforms carved into pale warm limestone, two-line layout centered — 'CHARLES' on the first line, 'STREET' on the second. Letter serifs are the natural termination of flat chisel cuts, slightly flared. Fine calcite grain and warm ivory patina on the stone face; fresh chisel sections reveal lighter stone against cream-ivory weathered exterior. Warm directional sidelight from upper-left casting fine shadows along each letterform edge. Background: same pale warm limestone surface, fading to warm deep shadow. Museum-quality classical inscription aesthetic. Vertical 9:16.
