This is a Fostoria Century snack set of three plates and four cups. There were four plates, but I had an accident in my shop and one was destroyed. Each plate is 8 1/4" wide and the cups are 3 5/8" x 2 1/2." All the pieces are in excellent condition with no chips or cracks. Century was made by Fostoria from 1950-1982. It is an elegant glass pattern.
