I dunno, ever watch Antiques Roadshow on PBS, when they have people bring in toys they were given as kids from the 1930's and 40's that are still in new condition in the original box?
Some amazingly responsible kid had the restraint and foresight to take perfect care of the item, as well as keep the original box. I was never such a kid, but some people are just this way even as kids. probably far less than 5% of the population. Who are responsible for nearly 100% of the antique toys that come up for auction in perfect condition.
