Is there a store that sells pictures, posters... of skyscrapers or skylines of US cities. Better yet, is there an archive I can access of old blueprints?
I know for a fact that you can pick some really nice pictures at the Museum of the City of New York on 5th Avenue and E.103 Street. Also, the Avery School of Architecture at Columbia University should have pictures and blueprints.
