Here is an old small "waiving bear" porcelain bottle top or stopper.  It stand about 2 1/2 inches tall and the stopper end is about 9/16th inches wide at the end.  The stopper is in good condition but shows some residual porcelain and seam on the side near the bottom.   Please see pictures and ask any questions.

  

Thank you for looking.   (Inv 23,574)
