Agnews

Thomas Agnew & Sons was established by Thomas Agnew in Manchester in 1817, and opened its London gallery in 1860, where the firm soon established itself as one of Mayfair’s leading dealerships. Since then Agnews has held a pre-eminent position in the world of Old Master paintings, and was instrumental in promoting contemporary British art in the late 19th century.
