A rare miniature portrait of Mozart will be auctioned in London on November 20 by Sotheby’s, according to a recent report published by The Guardian.

The 21-year-old composer gave the portrait to his 18-year-old cousin Maria Anna Thekla Mozart, with whom he had a fleeting affair, as the article mentions adding that “With his pink cheeks and bright eyes Mozart looks positively cherubic, the very picture of a young man in love”.

The 4cm portrait was painted by an unknown artist in 1777 and has been made on ivory while it still has its original bezel and glass.

It will be the main piece of the auction “Music, Continental and Russian Books and Manuscripts sale” and is expected to fetch between £200,000 and £300,000.
