The president of the Swiss branch of the International Council of Museums called the decision to sell the Cézannes “outrageous.”

The Swiss branch of the International Council of Museums (ICOM) has issued an official letter in protest to the Langmatt Museum’s decision to sell three prime works by Paul Cézzane at Christie’s New York in November, the Art Newspaper reported Thursday. The museum has said the sale will save the Baden, Switzerland-based institution from going under and having to permanently shut its doors.
