Antique salesman sample sofa

i fell in love with this ten years ago in an antique shop. I was told it was a doll sofa.  Since then, someone who saw it told me it was a rare salesman's sample of a sofa.  When i figure out how to use my new digital i can post pictures.  It is upholstered in a burgandy-ish velvet. I do not know if velvet is original.  Just curious.  Can't find anything like it in many online searches and auctions.  Thanks for anything you can tell me.
