Fine Art: Magritte's dove of peace is an image for our times 

Des O'Sullivan previews the London sales, including Christie's Art of the Surreal event 

Magritte's Le retour.

Painted around 1950, Magritte's dove of peace remains a powerful image for our times. There is plenty of confidence at Christie's that his striking work titled Le Retour will spark universal interest at its Art of the Surreal sale in London on February 28.

Over the course of his career, Magritte became adept at converting his vision of the mysteries of the world into pictures that, through icon-like simplicity, conveyed their messages in ways that are more striking.
