In July, Macy’s State Street began moving its Fine Rug Gallery from the musty, outdated ninth floor down to the freshened-up eighth, in the process expanding its selection of contemporary rugs and adding new collections from Memeni, Nourisan, Sphynx by Oriental Weavers and more. Yesterday, the gallery re-opened for business, and in honor of the occasion, customers who come to explore Macy’s uppermost retail floor will take in a piece of 1933 Chicago World’s Fair history: a famous 12x15 Karastan 791 rug. The manufacturer’s 791 pattern with its “tree of life” design was introduced in 1932 and made using a new-at-the-time power-looming technique. At the 1933–34 fair, some 12,900,000 pairs of feet tromped across the rug in possibly the most rigorous wear-test imaginable. Afterwards, it was returned to the mill in North Carolina and washed on one side only to demonstrate its remarkable durability. See the 791 through October 24.
