Mostafa Hassani designed the key as a symbol for Rouhani's presidential campaign.
In an interview with local media, he said about the symbol "The design helped grow Rouhani's campaign advantages conspicuous. A look at all Iranians’ thoughts as a key to unlock problems is the very thing that is today seen in Dr. Rouhani's approaches. This uniting look was crystallized in the key for prudence.”
Hassani stated that the key symbol has been an opportunity for using the entire people’s abilities for promotions, adding "People had found out that by casting one vote, they would get more than a president, that being a good feeling and hope in the future.”
"People need a persuasive reason to vote for the one concerned,” Hassani asserted.
He further added "To have a symbol surely does not mean to be accepted by people. Choosing a symbol is a completely expert job and takes much research and investigation. But to be sure all candidates had valuable strong points.”
He also pointed to Mohsen Qalibaf and his potential symbol and said "If I were to recommend Dr. Qalibaf a symbol, I would have given a watch. That is because one of Mr. Qalibaf’s abilities is his precision and speed. In the Municipality of Tehran he proved that he respects people’s most important asset, which is their time and life, and that he keeps his word.”
