Commerzbank is auctioning next month a bronze sculpture worth an estimated €20m ($29m). The move represents the latest example of financial institutions selling parts of their art collections.

The lifesize Alberto Giacometti sculpture, L'Homme qui marche I, is going under the hammer at Sotheby's sale of impressionist and modern art on February 3, with a €14m to €20m estimate, according to the auction house.
