Bust of Peace, the last piece of Antonio Canova, is due to be auctioned by Sotheby’s in London on July 4. Canova (1757-1821), who was born in Italy, is one of the most celebrated and expensive sculptors of the early 19th century. /VCG Photo

It is the first public outing in 200 years after the masterpiece, which is expected to fetch well over 1 million UK pounds, was displayed in 1817. /VCG Photo

The artwork was accomplished in 1814 and was given by the creator to his friend, aka Lord Cawdor John Campbell, as a gift. The bust was created for celebrating the stepping down and exile of Napoleon, before Europe had regained temporary peace. /VCG Photo

The white marble of the Canova’s Ideal Heads had been stored in the Campbell’s home until their castle was demolished in 1963. /VCG Photo
