I saw this wig head while browsing through a Hudson's salvage goods store. It's definitely based on vintage Barbie, though it's not an official product. It's dirty and worn, but apparently a modern product. I left it on the shelf, the price was just too high. Maybe the price will be more realistic next month. Hudson's sells everything other stores couldn't sell for one reason or another, at progressively discounted prices. This week was only 40% off.
There are actual deals, I ended up buying a bunch of ant baits for 49 cents per 4-pack. That's not very glamorous.
