Trolls have been a part of folklore forever--as bad and mischievous creatures who lived in caves, in logs, and under bridges. Trolls are believed to be good luck, which certainly has helped the sale of troll dolls--troll dolls can be found in houses, in cars, even at work, purchased with the hope that they will bring luck to their owners. Trolls in their collectible form were first created by Thomas Dam and his family, in Denmark in the 1950s. The first Dam trolls were carved in wood. Later, they were made of soft rubber, and finally, vinyl. The trolls made by Thomas Dam's company became known as "Dam Things," and these are the most popular trolls with collectors today. Most collectors believe that the Dam Thing trolls have the most character, the best clothing, and the highest quality.
