Agnew & Zanetti
The firm began as a print and publishing partnership between Thomas Agnew and Vittore Zanetti, founded in Manchester in 1817 as Zanetti & Agnew. The name changed to Agnew & Zanetti in 1828 when Vittore Zanetti retired and Agnew became senior partner.
Joseph Zanetti left the business in 1835 and the firm became Thomas Agnew & Sons Ltd, focusing primarily on fine art dealership.
