What does Gandalf from The Hobbit and Lord of the Rings look like?

Answer 1

The best we can do is to put the general description of a hobbit from the book:

They are inclined to be fat in the stomach; they dress in bright colours (chiefly green and yellow); wear no shoes, because their feet grow natural leathery soles and thick warm brown hair like the stuff on their heads (which is curly); have long clever brown fingers, good-natured faces, and laugh deep fruity laughs (especially after dinner, which they have twice a day when they can get it).

Answer 2

This is the description of Gandalf from The Hobbit: "...an old man with a staff. He had a tall pointed blue hat, a long grey cloak, a silver scarf over which his long white beard hung down below his waist, and immense black boots"

Answer 3

The actual description in The Hobbit is scanty at best: "In a great hall with pillars hewn out of the living stone sat the Elvenking on a chair of carven wood. On his head was a crown of berries and red leaves, for the autumn was come again. In the spring he wore a crown of woodland flowers. In his hand he held a carven staff of oak." In artistic renditions, he is usually portrayed as blond. In the related links are a selection of Thranduil representations by various fan artists.

Answer 4

Balin was "a very old-looking dwarf with a white beard and a scarlet hood." (The Hobbit, chapter 1.)

Answer 5

Yes, they are the same person. Balin took his treasure and intended to re-establish Moria as the capital and home of the dwarves.
