Paper Fetish Places in NYC

I'm one of those people who fetishizes beautiful paper and there's nothing to do for it but to make a list of the most astonishing places I know. feel free to add your own.

1. Kinokuniya Bookstores
10 W 49th Street, between Fifth and Sixth Avenues
The place is easy to miss because it's on a side street at Rockefeller Center. The books are only in Japanese, so if you can't read Japanese, you can certainly appreciate the visuals. Uptairs they have a sophisticated assortment of origami manuals and an astonishing array of beautiful origami papers.
2. Chisholm Gallery
55 W 17th Street (Sixth Avenue, sixth floor)
Gallery specialized in antique advertising paper from the United States and Europe. They have some real gems in the collection: posters, point-of-purchase displays, and enamel signs from the best vintage advertising years: the 1920's and 1930's.
3. Winter Works on Paper
160 Fifth Avenue at W 21st Street
By appointment
Unique gathering of images by art dealer David Winter, prized as a source of eccentric imagery and botanical specimens.
4. Pierpont Morgan Library
29 E 36th Street at Madison Avenue
Breathtaking collection of rare books, manuscripts, and old master drawings. You just don't see the smudges and fingerprints of DaVinci in the reproductions, you have to get up close and personal.
5. Pearl Paint, 3rd floor
308 Canal Street
Always a pleasure to deal with whoever's manning the paper nook, since the staff is knowledgeable and helpful. If you know your papers and know what to ask for, chances are they'll pull something out from a bottom shelf that you never knew existed.
