Vintage does not always mean "good taste". Nothing screams "TACKY!" like a set of Bi-centennial glasses where George Washington is viewed crossing the Delaware through a cocktail.
These are not expensive or even unusual, but they do make me smile each year as I sip a little bourbon and soda while watching fireworks off the balcony. They are in great shape, but then again they are so ugly that they are only used 1 day each year.
