| 表面の説明 | The state emblem of the German Democratic Republic is centrally displayed in the field, consisting of a hammer and compass surrounded by a wreath of grain, symbolising the worker-peasant state. The circular legend DEUTSCHE DEMOKRATISCHE REPUBLIK runs along the upper periphery, while the date 1974 and the denomination 5 MARK appear along the lower periphery. The design is rendered in a clean, modernist style with sharp relief against a smooth field. |

| 裏面の説明 | A detailed technical rendering of Philipp Reis's pioneering telephone apparatus dominates the field, depicting both the transmitter unit with its conical horn mouthpiece and electromagnetic coil mechanism (labelled A, S, and B) in the upper portion, and the receiver unit with its electromagnetic induction bar below (labelled C), connected by a schematic wire. The name PHILIPP REIS is boldly inscribed across the centre of the field, with the dates 1834-1874 appearing in the lower exergue, commemorating the centenary of the inventor's death. The composition references Reis's original 1861 apparatus diagrams with a precise, engraved technical illustration style. |
