Iranian art students from the University of Shiraz pose with a huge origami dinosaur they created at the Shahre Aftab Art Complex on November 11, 2018 to mark Origami Day.

The five-meter high origami was created from a sheet of paper measuring 100 square meters under the supervision of Reza Sarvi, a professional origami artist. 

November 11 is annually celebrated as Origami Day in Japan, home to the art. 

In addition, origami institutes such as the Japan Origami Academic Society, the British Origami Society and OrigamiUSA celebrate a period from October 24 to November 11 as World Origami Days (WOD). (IRNA/Reza Qaderi)
