Perforated metal chairs René Malaval 40-50's

Set of 4 outdoor chairs model "radar" of the french designer rené malaval published by bloc métal. These chairs illustrate post-war french industrial design. Robust, with arched tubular base and thick perforated sheet metal... In a very "upcycling" spirit, rené malaval, a welder by trade, had the idea of using the sheets of sheets discarded after their perforation (for the manufacture of ammunition caps during the second world war?). In good general condition. One foot of one of the chairs is pinched on its end. Separate photos of each chair available. Sold in their juice (paint of green origin with traces of wear and oxidation).
