Iranian traders play backgammon as they sit outside a shop in Isfahan's handmade carpet market, 450 km (280 miles) south of Tehran November 14, 2011. Persian carpet weaving is a historical part of Iranian culture, dating back to as far as approximately 2,000 years ago. Persian carpets can be mostly divided into three size groups: large (3x4 metres), medium (2x3 metres) and small (1x1.5 metres), which is called Ghaliche.
