| 裏面の説明 | The reverse pays tribute to mathematician and computing pioneer Alan Turing, centred on a portrait of Turing alongside technical imagery evoking his foundational work in computer science, including representations of early computational concepts and binary patterns rendered in olive-green and teal tones against a complex guilloche background. A sunflower motif and cross-sections referencing Turing's mathematical biology research appear in the design, along with his birth and death years and a facsimile of his signature. |
