Large sideboard  made in the 1930's in France , this type of sideboard was quite fashionable in France around this period .I looked for reference on line and in books about this sideboard  and I think it is most likely a designer creation.  You can see the influence of  Dominique and Dupre Laffont : simple line with strong contrast .I did not find this piece in the catalogue of Levitan or Le Bucheron  which was with Les Gallerie Barbes the main distributor of mass produced furniture of their time .It is not one of the piece widely built and distributed that I learn to recognize through the years . It is interesting to notice it come in 2 parts for easy transportation .The marble top is grey , large original harware with keys  .
Size H.34.5 x D.16x L.85 Good antique condition
