This dark green depression glass is a 3 piece set with gold trim on every piece. The gold trim is in excellent condition. The underplate has a 10 sectioned design and is 7 1/4 inches across. The bowl's shape compliments the underplate and is 5 1/2 inches across and at the handles is 6 1/2 inches across. The gold trim at the base of the mayonnaise bowl sits inside the underplate's gold trim design. The underplace is not completely flat. This is a very nice piece for that depression glass collector. I have a no return policy so if you have any questions please e mail me. I don't know enough about depression glass to say who the manufacturer was. The photos show the items upside down as well as right side up. i am paying the shipping and insurance and it will be carefully packed. We must collect 6% Pennsylvania Sales and Use Tax at checkout. Thanks for stopping by!
