Sources & verification
Partially verifiedSéfi distinguishes inverted watermark sheets from reversed and inverted-and-reversed sheets. The lower bound is the 1901 single-Crown-CA issue; the upper bound is documentation in 1913. These are evidence bounds, not a continuous-production range or a known first-sale year. No shade, gum or plate identity is inferred. The watermark state requires reverse inspection; any ordinary front illustration is design-only.
Research notes: The 1901 group heading anchors the base design. The collectible's first appearance is unknown within its explicit documentary bounds.
Image & attribution
