Early set of 6 original stamped Multipl's metal chairs by Joseph Mathieu with art nouveau seats

Set of 6 original multipl’s metal bistro or garden chairs with multipl’s lyon stamp on the back. The wood art nouveau seats indicate a very early date for the chairs (one seat is different). Beautiful original mottled blue-green colour. The chairs are stackable. Very good condition with normal signs of age and use, stable structure.
