Beautiful artistic puzzle called "Ella" by artist Ashley Joi Whitley.  Featuring a princess with a beautiful dress and afro, sitting ready for a Ball.  Gorgeous art style with lots of detail.  Created by Spin Masters, this puzzle has ALL 500 pieces, which are slightly larger than normal, with a larger shape variation than standard.  
This puzzle has ALL its pieces, and the included poster.  This item has been used but is in excellent condition.  I have personally assembled & inspected the puzzle to verify this.
