I don't know if this is sooo exciting - I more or less grew up with my grandparents (in Germany) in the 1970's. Finding third-Reich stamps and stuff like that in cabinets and drawers was an everyday occurrence, mainly because the old folks hadn't gotten around to cleaning out a lot of the stuff. By this article's definition I suspect most older homes in Germany are unique archeaological treasure troves. Also, I don't know how much of this is really "archeology" - there's still plenty of people from that era around
Cheers,
