I believe it is rare that you find jewelry by Willy Winnaess that is not from David Andersen. These simple Vintage Modernist Sterling Silver Screwback earrings are hallmarked with the W trademark of Willy Winnaess Norway, who was a designer for David Andersen. They measure appx 1 1/2 inches. Also marked with 830S for silver content. They are lightweight, simple but strong design.
