CHAMPAGNE. Important set of 27 posters of different sizes, most of them printed in Troyes during the First World War, or in the two or three years following its conclusion: rationing (milk, sugar, bread), various loans, obligations imposed on the farmers; two are important because they impose an enlistment of the able-bodied men from 16 to 60 years old in the army. One poster is illustrated by SEMPE (worm work on a fold).
