Fav art bookstore in the city (and the world?). Great place for inspiration and reference art, both new and vintage finds. Not very cheap but mostly quite worth it.
Giant dinosaurs. And the rest of the museum is great if you also like giant whales and outer space and especially the life size dioramas of animals and cave people, which might be the very best Art in all of the city. Sigh.
My favorite place on Bedford Avenue, this bookstore has both new and used titles. If you're patient and look close enough, you can usually find a book that's worth more than they're asking. Not to mention their stellar selection of magazine titles. Good for design, art, photography, sociology, fiction, and everything in between.
