Focus on Tête qui regarde and explain the Examples.
Examples are held in several public collections, with a marble example held by the Stedelijk Museum in Amsterdam, and a plaster example at the Fondation Giacometti in Paris.  The Museum of Modern Art in New York has a plaster model and a cast from a series of six bronzes.
A plaster example was the subject of an episode of the BBC television programme, Fake or Fortune?. It had been damaged and repaired (more than once) and covered by white emulsion paint. In the original airing of the programme in 2018, the Giacometti Foundation took a preliminary view that the sculpture may have been an original work, but the extensive damage made it difficult to justify that conclusion. A revised and updated version of the programme was shown in 2019. The paint had been removed, revealing a Giacometti signature and date. The work was authenticated by the Foundation and sold at Christies for over half a million pounds.
