We can’t say much more about this sideboard other than it was produced ca. 1929 by Thonet Frères Paris. Was designed by Bruno Weil. And is fantastic.
In essence a double-decker glass and metal table we find it one of the most delightful examples of modernist furniture; and one of the few that hasn’t lost any of its freshness over the decades.
This is example was photographed in the Grassi Museum Leipzig exhibition “Art Nouveau to Present”
