A “jiggling” turtle is in constant movement under the glass of this white metal drum shape with stud shank. Textured silver foil is the background for the turtle. See the article by Peggy Ann Osborne, NBB October 1987, p. 137-139 for more information about animated studs. This is the last of a collection of these jigglers that we have received for auction. Est. selling price is $100-200.
