In case you can use them, I have two of these right now and they are completely original pieces. I purchased them in Belgium many years ago and have finally installed them. You can see how useful this could be. It cantilevers out from the wall and is supported by "newly chromed" supports both as legs going down installed into the wall, and also in the frame that supports the marble. Very clean, almost Bauhaus, almost mid - century but they are truly from the Art Deco period. The marble is black with some slight variations of white running through them. Find the right spot and you've got a winner. Measurements: 25.5" W x 15" D (you can install them at any height, but must be at least 24" from the lower supports to the top of the marble)!
