20.  MAST Books

1-MAST Bookshop Untapped Cities AFineLyne

Opened in 2010, MAST Books occupies a small, but well-organized, space in the East Village. The owners’ love of the arts has led them to specialize in used and rare 20th and 21st Century books related to art, photography, design, fashion, cinema and even poetry. Despite the constant stream of customers, the books are neatly displayed and all in very good, if not excellent, condition. Located at 66 Avenue A between 4th and 5th Street, Noon to 10 pm.
