More proof of "what goes around, comes around." It may have escaped your notice, but there's quite a resurgence of Troll Dolls recently. They even have a new movie out. Really.
Back in the 50s, a Danish fisherman named Thomas Dam amused himself by carving cheerful little wooden renditions of the legendary monster that hid under bridges to eat humans. His wife recognized their marketability, and after selling them door to door for a while, he opened a factory. What a hit!!
Originally, the trademark wild hair was made from wool. In 1964, it took the entire wool harvest of Iceland to meet the need.
And that's all you need to know about Troll Dolls. How's your bidding knowledge?
