A booklet of Mozart sonatas was withdrawn from auction after a claim that it was donated to a charity shop 'in error'. The first edition of the Sonatas for Keyboard and Violin K10–15, dating from 1765, had been expected to fetch up to £3,000 in the sale at Sotheby's in London on 8 June.

A volunteer at the Oxfam music shop in Reading found the rare booklet in a box of donated sheet music, but a spokesperson for the charity said that a woman had come forward claiming that the music was donated 'by mistake'. Oxfam withdrew the sonatas from auction pending an investigation of the claim. According to the spokesperson, the charity has an informal goodwill agreement with donors that if they want an item back that they have donated, the charity will return it.
