DARLING 1950s Knickerbocker "Skippy" rattle -- mint in box -- New Old-Store-Stock
 
These sweet little ducks want to celebrate holidays with you... BABY NEEDS A STOCKING STUFFER~
 
Give Skipper a good shake and he/she gives a healthy rattle to keep your baby doll amused.
 
I have one each RED, BLUE, and YELLOW... probably have more but this is all I found today.
 
Each measures 2-1/2" x 3-1/4"
