I love the artwork in the TOR books, especially the ones of the different locations. If I should point out some of my favorites, I would say that the birds eye views of Imladris (from the Rivendell book) and the one of Lake-Town are high on the list. And the one of the Dol Goldur gate... and the Hall of the Elvenking. And... well, you get the idea.
But, I noticed a new piece of artwork in the revised core book, on page 52. It seems to be of a Dwarven hall entrance. Is this a specific location in the setting? It seems too small to be Erebor. But if it is a different Dwarven hall, which is it?
