Among them will be this sideboard, model #2135 number 2 from 1930, by the French Art Deco designer Emile-Jacques Ruhlmann (1879-1933).
It measures 5ft 7in (1.7m) wide, is signed on the back, has doors which open to a shelved interior, a brown marble top and is set on a gilt bronze-mounted pedestal base.
The sideboard comes with a copy of the Ruhlmann receipt and is estimated at $50,000-100,000 in Windsor, Connecticut.
