Multipl's chairs by joseph mathieu 1927

Set of 3 metal stacking chairs dating from the first manufactures of the famous multipl's chair created by the lyon engineer joseph mathieu. This model constitutes an immolation because it is the first patent filed in 1922 of stacking chair. They were probably still made in a traditional way between 1927 and 1929. The welds are visible, the backrest is v-shaped "hollow" and especially the perforated wooden seats are original, which is rare. The metal has been stripped and has a very beautiful patina. The foundations deserve a small restoration.
