Original design
Christian Funke describes the design as follows: "It displayed a map of Iran that was decorated with an atomic model showing the orbital paths of electrons around the central nucleus. Besides the atomic diagram, a Persian translation of a tradition (hadith) of the Prophet Muhammad was inserted into the map too. The inscription “Persian Gulf” appeared on the southern shore of the Iranian map."

Redesign
According to Funke: "it shows the main entrance to the university [of Tehran]. The empty space beneath the two arches in the banknote is filled with a couplet from Ferdowsi. Both the Persian content and its English translation are inscribed on the note: “Capable is the one who is wise, Knowledge makes the old heart young”."
