Otto Versand, the German catalog firm, has formed a joint venture with Harrods, the British department store, to sell Harrods products online. U.S. cataloger Spiegel Inc., in which Otto Versand owns a majority interest, will provide customer service and marketing support in North America. These services will be handled in other countries by other Otto Group companies. Roughly 200 Harrods products will be offered to consumers in the United States and Canada during the holiday season. The effort will be supported by a catalog mailing in both countries. In a separate development, Spiegel has retained Aramex International Ltd., an express and freight forwarding company, to distribute its catalogs throughout the Middle East.
