To those who are unfamiliar with Bone, what does this license bring to Telltale? How would you characterize the stories and visual style of Bone?

Bone offers a lot to Telltale and adventure games in general. The strong characters and storyline of the comic are very much in sync with the kinds of worlds and experiences that Telltale is interested in creating. The story is an epic tale, somewhat in the vein of Lord of the Rings but infused with a lot of humor and steeped in an artistic style reminiscent of Walt Kelly’s Pogo.

On which Bone comic(s) will the story of the game be based?

We’ll be telling the entire storyline outlined in the original comics, in an episodic manner. So the first game will deal with the beginning of the books, "Out from Boneville".

We're talking about a graphic adventure game, right? What kind of engine and interface can we expect?

Yep, it will indeed be a graphic adventure game. The interface and engine will be of the point and click variety.
