I had a super hero at Six Flags yell at me for being "inappropriate" yesterday.

I recently came across my wife's childhood collection of "Dolls from around the World". These were given as gifts in the mid 70's. I would like to know if there is any information on where they are from and what if any value they might have. They are each about 7 inches tall and dressed in the countries style. Each of the dolls eyes "roll" back (open and close) and they are made of plastic. Each is in it's own box that says dolls of the world, collect a complete set.
