The largest collection of works by David Bomberg ever to be auctioned is to go on sale in London next month.

Thirty-two paintings and drawings will be offered by Christies.

They are expected to realise around half-a-million pounds. Proceeds will go to Hadassah, a charity raising funds for the Hadassah Medical Organisation in Jerusalem.

Bomberg, the son of Jewish immigrants from Poland, was one of the leading artists of the avant-garde Vorticist movement before the First World War.

Mark Addleman, director of Hadassah, described the sale as “an amazing opportunity for us. Bomberg is a fantastic artist”.
