Letter: Consenting life masks

Sir: Jane Wildgoose is in error in describing the National Portrait Gallery's masks of Blake and Keats as "death masks" ("Is it wrong to use a dead body for art?", 18 August). Both were made when the subjects were still living, and, more to the point, consenting participants in the procedure - which cannot be said of the subjects featuring in Anthony-Noel Kelly's artefacts.

(Though to judge from Blake's expression, he was clearly having second thoughts about subjecting himself to the process.)
