I don't have too, I know that anything that's over 10 years or rare can be considered vintage. I collect a lot of things, so I am sure that these are. Vintage does not mean old, it means Vintage can mean an item is of a certain period of time, as in 'vintage 1950's' but it can also mean (and probably always should) that the item exhibits the best of a certain quality, or qualities, associated with or belonging to that specific era. Era of the 90"s. I hope this helps.
