The shawl was designed by Couder and manufactured by Gaussen for the 1839 Paris Exhibition. "Nou-Rouz" was a Persian holiday, celebrating the Spring equinox and the new year. The design meant that the weave was extremely complex using over 101,000 jacquard cards. It appears that the successors of Gaussen, who died in 1843, also made examples of the design during the 1840s, with later style harlequin borders.
