I shop online a bit, Etsy being one of my favorite places and I find myself shaking my head at what some people consider vintage or antique. Vintage in particular seems to have a different meaning everywhere you go. Some folks are saying that items 7 years old or older are vintage and items 50 years or older are antique. Others use vintage with the year: vintage 1973 or vintage 1980.
Well I beg to differ, I've always been told that vintage means at least 35 years old, otherwise it's just "used".
As for antique, I use the U.S. government definition. They say that for Customs purposes an item must be at least 100 years old to be considered Antique, and if it is, then it can be imported duty free. We do most of our antique shopping in England and I'm careful about buying real antiques.
So Vintage = 35 years old or older
Antique = 100 years old or older
That means I'm Vintage, but not quite Antique.
