When it comes to art books, the new Elliott Bay (and the old Elliott Bay, for that matter) is not a magical wonderland where you can find every single obscure classic and all the new stuff, too. But it has a stronger collection of what you're looking for than any other location in the city, it has basically all the relevant mags, and then, you're liable to stumble into stuff you had no idea you'd discover.

Such as a book of hand-drawn movie posters from Ghana.

And the incredible, only-recently-published "Red Book" by Carl Jung, which deserves its own post.
