From the publisher:
Based on the popular troll dolls created by Thomas Dam, Trolls is a 3-D computer animated musical comedy from DreamWorks Animation, directed by Mike Mitchell (Shrek Forever After). Princess Poppy (Anna Kendrick) is an upbeat, if slightly naïve, Troll who inherits her crown on the day her people face the first challenge that can't be solved with a song or a hug. Accompanied by Branch (Justin Timberlake), she ventures "far beyond the only world they have ever known" in a quest that tests their strength. Full of playful designs, The Art of Trolls showcases hundreds of pieces of concept and production art to illustrate how DreamWorks's team of talented artists created an enchanting reinterpretation of the Trolls phenomenon that has gripped popular culture for decades.
