Mozart charity shop find only 'one of 10 in the world'

When an Oxfam volunteer at the charity's Reading shop opened up a box of donated sheet music, she knew almost immediately there was something special about the tatty score on top.

Elestr Lee, a musician, quickly spotted the printed composer's name at the bottom - Wolfgang Mozart.

She researched the inscription on the front, which was in French and dedicated to Queen Charlotte, wife of King George III who reigned from 1760 to 1820.

It read in French that the booklet contained 'six sonatas for the harpsichord'.

To her delight Sotheby's confirmed that the discovery was a first edition piece of music that an eight-year-old Mozart wrote on a visit to London in January 1765.

The booklet was to be one of 190 musical items put up for auction at Sotheby's in London on Wednesday....
