Mies Van Der Rohe coffee table

Barcelona (style) coffee table designed by Ludwig Mies van der Rohe and produced by Knoll International circa 1970. The tables are mass produced and mass replicated. They are never signed so i'm not 100% sure this is a orginal one. It is an old one (patina on the chrome) but i'm never 100% sure about this tables. 
 
The table was originally created in 1930 for the Mies-designed Villa Tugendhat in Brno, Czech Republic in 1930.
 
It's a table with clean lines and a elegant design.
