古びた羊皮紙に描かれた一輪のマリーゴールド植物画

A single Indian marigold depicted as a museum-grade botanical engraving, rendered in Albrecht Dürer–style charcoal engraving, with dense cross-hatching, visible hand pressure, and slight line irregularities indicating age and manual craft. The illustration must show clear paper grain, off-white aged parchment texture, restrained contrast, and sober tonal discipline. Lighting is neutral and documentary, with no dramatization. The marigold is isolated, centered, and treated as an archival specimen from an old temple register. Orange pigment only, no other colors present.
