Olszewski made approximately 22 Hummel miniatures, only one of which has four girls and is called Ring Around The Rosie/The Maypole Dance. Iis a very rare piece. It stands 2 7/8" while the base is about 7/8" diameter. The miniature comes mint in its original sealed plastic with First Edition Certificate and original box. The mold number under the base is 286-P while the balance of the base shows "Limited Edition - 10,000 pieces Goebel Germany 1994" This one was shipped to me from Germany in a Hummel box which is has red tape across it but the piece is perfect.
(There is also a display for sale for this piece with a glass dome and a music box which turns the pieces around while playing music. I just purchased it and had never seen one before.)
