In the month of June, Ruinart is revealing a limited edition of its iconic vintages signed by French artist Claude Viallat. The painter has applied his flagship forms and colours to second-skin casings for the R de Ruinart magnum. Signed and numbered, each case is available in 50 copies. Already exclusively available from the Maison Ruinart in Reims, these limited editions will then be found at La Samaritaine in Paris from September. (De 700 à 900 €). www.ruinart.com
