Tanja Maduzia’s mother sent her to an auction to bid on sconces for their antique store. Tanja returned, $15,000 later, with an unusual piano and no sconces.  The piano, a “giraffe” model from 1865, was built in Kentucky and has the upright curved lines of a wide harp. The Maduzias spent $10,ooo to restore it over the years and now, with the store closing and Tanja needing to pay off emergency room bills, it will go on sale for about $30,000.  Appraisal value is $50,000.
