Zsolnay 1870's Duck Basket

I recently purchased this beautiful and unique Zsolnay piece.  I've searched Ebay for anything even closely resembling this duck, and no luck....It is interesting because this piece uses both the well known Zsolnay detailed and ornamental flowers COMBINED with the eosin glaze that Zsolnay is famous for.  The piece is in great shape.  I'm wondering if there is a Zsolnay collector that would be interested in purchasing it from me.  I'm not sure of its value and would love input.  The overall heigth of the basket is 9" and it has a width of about 8".  Its a larger Zsolnay.  It's also imprinted on the bottom the number 1517, which dates it to the 1870's.  Any additional information would be greatly appreciated.  THANK YOU!
