Oriental antique rugs have always been in great demand as an investment value. We mention here some of the most famous and remarkable carpets collections of the Rockefeller or John Paul Getty families in the USA. In art auctions e.g. Sotheby's, Christies or Rippon & Boswell antique rugs often reach astronomical prices. In the 1970s the Persians themselves repurchased old Persian and non-Persian rugs to preserve them as a cultural asset for future generations. Our collection contains some great pieces woven around 1900. Unique rugs like these can yield multiple added value over time.
