I'm have a similar thought to you r15324, so I just did a quick google and a there was a plethora of differing opinions. The disturbing thing is though, the number 40+ kept coming up, so that means I have to classify myself as vintage
my personal rule of thumb has always been, anything made before I was born! that way piggies are never vintage - it works out quite handily, no? (^(oo)^)
^ loki, don't say that... Or I'll have to classify my parents as vintage as well... Lol
for me, 10 years to be "vintage," and "antique" for things older than i am
