ATLANTA-- Great toys are timeless. Take the troll doll. You remember: the ones with the plastic bodies and wild hair. They first showed up in the late 1960s when a Danish woodcutter named Thomas Dam made one for his daughter for Christmas. The mass popularity of the doll and some copyright issues lead to a flood of imitations. They came back in the late 1980s. And they're about to have a third comeback.

Christopher Byrne arrived at the 11Alive studio with a few trolls, a 6 Million Dollar man worth $300, and a LeapPad Ultra. It makes sense for a toy historian. He's shopping his new book, "From Hula Hoops to He-Man to Hungry, Hungry Hippos".
The book features more than ninety of the most-loved toys from generations past. It's filled with history, trivia, and background on the toys that shaped our young lives.
Byrne is also keeping an eye on the future. He's predicting the LeapPad Ultra and the Cra-Z-Loom will be two big sellers this holiday season.
