I think 100 yr or more for or something that's old enough that it's back in style again, like fashion - Vintage 1970's clothes. (Blech.)
Although, the 70's aren't that far from being 50 years ago.
That's so ....wow. Huh.
Hm-m-m. When I hear "vintage" 1970's clothes," I assume that these items actually date back to the 70's: they are genuine 1970's clothes (as opposed to clothes made in 2011 to look like 1970's clothes).
It goes back to my response to Jan's question: if a person is selling a current
reproduction of a Singer sewing machine from the past, would they be justified in saying it was "vintage?"
