When Shahen of Iran in may 1959 visited the King and Queen of Denmark, he brought as a gift a georgeous Nain-rug in the size 216x319 cm handknotted with over 1 million knots pr. m2. The rug is created at the famous Artschool in Isfahan. The pile is wool, but the device of the Shahen has been woven into the border. This is by the way a fine eksample to show that the Persian rugs are named after the design, regardless the geographic placement of the producing.
