RE: terminology such as "vintage" and "antique" I do think the definition for vintage is changing, and may depend on where you are selling/buying. I used to sell on Etsy, and the site rules stated that "vintage" could refer to anything 25 years or older (If I remember correctly. I know that it allowed some things from the 1980's to be labeled "vintage").
I think "antique" was reserved for items 100 years or older.
