I purchased these two mugs recently at an estate sale in my area. The printing states that they are from the Spring Formal of 1989. The printing on one is starting to fade, but is still very readable. They measure 6 1/2 inches tall and are 4 inches across the bottom. They are made of a heavy glass and I do not believe they will fit in a flat rate box, so please ask for a shipping quote. Buyer to pay delivery charges of $10.00. Insurance suggested. Seller will not be liable for uninsured items. All items in my listings come from either garage or estate sales. I do not know if they came from homes where smoking or pets were present. All items are sold in the same condition as when I received them.
