Polish rugs and carpets

Mr. John D. Rockefeller, Jr., has the most notable group of Polish rugs. Mr. Widener of Philadelphia specialized in Ispahans. Mr. Andrew Mellon and Mrs. McCormick of Chicago made large and valuable collections.

Mr. Mellon's is now in the National Gallery in Washington. Mr. Benjamin Airman's is in the Metropolitan Museum in New York, as is part of Mr. James Ballard's.

Mr. Ballard of St. Louis was not only a collector, he was a scholar and an authority. He traveled all over the world in search of rare pieces. The finest prayer rugs of Turkey were his specialty, though he had ex­amples of Persian, Indian, and Chinese as well.
