We created the One posters by bringing together common art forms from both Christianity and Islam. We studied the history of both religions and chose 8 art forms from architecture, culture and traditional elements, such as mosaics, stained glass, door carving, calligraphy, beads, carpets, relief and dome. We merged their individual styles seamlessly to create one poster. The art forms were adapted from churches and mosques around the world to show that there's so much more that unites us than sets us apart.

The One posters were adapted from various churches and mosques around the world. The Byzantine mosaics of Palatine Chapel of Italy were merged with the Girih pattern mosaics of Bibi Khanym Mosque in Uzbekistan. The stained glass windows from Selimiye Mosque in Turkey were merged with Cocteau’s stained glass windows of Église Saint-Maximin de Metz in France. The doors are inspired by the Hasan 2 Mosque of Morocco and San Augustin Church of Philipines. Similarly, other elements like beads, carpets, relief and dome from churches and mosques around the world were brought together on a poster which also became a sleeve for the One Book. The One posters were promoted at peace conferences and art galleries across Europe and Middle-east.

The campaign received a total of 53 million impressions. From sending the posters to influential leaders like Pope Francis, Antonio Guterres and Donald Trump, to placing it in between the church and the mosque, we reached 96% of the total population of Bosnia and Herzegovina, and 100% of its online population. The posters are now being promoted at peace conferences across Europe, Middle-east and Asia. Two weeks after the launch, faith leaders came together for a common prayer for the first time after the Bosnian War.
