Set of 4 “radar” armchairs by rene malaval circa 40’s

Set of 4 "radar" armchairs by rené malaval. Strictly original, no later welding, original rivets, only the blue paint, not original but old and patinated. The only thing missing on an armchair are the plastic pads. A real study in design...but comfortable thanks, among other things, to the perfect orientation of the backrest. Together become rare!.
