Ching Tsai Loo, (1880-1957) best known as C T Loo was an influential and controversial dealer of Chinese art and artifacts working during the first half of the 20th century. Moving from Shanghai to Paris at the turn of the century Loo established an antique business 'Laiyuan and Company' exporting high quality antiquities from China, and quickly detected a new market for early Chinese art.By the mid 1910's, following the effects of World War I on the art market in Europe, Loo had moved to New York where he rapidly became a significant figure in the art world, catering to the demand for Eastern works of art and introducing a large number of Chinese antiquities to museums, and private western collections.Provenance: This pair of vases was acquired from an estate sale in the 1950's by the current vendor's family. The vases are accompanied by a copy of a letter of appraisal from Russell Alberts of Ton-Ying & Company Chinese Antiquities, New York, dated 1967.
