This set of Sterling Silver Salt & Pepper Shakers is marked Newport Silverplate YB 69. Top is rounded and overall shape is atomic
There are plastic plugs on the bottom.
They are 3" tall and 1 3/4" wide at the base.
They are in excellent condition. They have never been used. They need a little more polishing, but I have found a too shiny surface is difficult to photograph.
I am including the receipt from Marshall Field & Co. Unfortunately there is no year, but I know it was very early 60’s. Original price was $5.25.
