A booklet of rare Mozart sheet music that was discovered in a
charity shop is to be sold at Sotheby's on Wednesday 8 June. The
second printing of a first edition of the Sonatas for Keyboard and
Violin K10–15 was found in a box of sheet music at the Oxfam music
shop in Reading. The sonatas were composed in London in 1764, when
Mozart was eight years old. They were first printed in 1765.
The sonatas are being auctioned by Sotheby's in its Music and Continental Books & Manuscripts sale this week. The sheet music carries an estimate of £2,000–£3,000. The highlight of the sale is Mahler's personal copy of the first edition of his Third Symphony, which has an estimate of £100,000–£150,000.
