"Maurice Realier-Dumas was a native Parisian… In his poster work, which is rather infrequent and rare, he adopted a technique, of simple lines, flat colours, and economy of design. Maindron said of him that he seems to derive his inspiration from Greek vases; and indeed, Champagne Mumm manifests a certain classic austerity that could well be described" (Wine Spectator, 38)
