H.A. Dunne and Co.
H.A. Dunne & Company, home of the H.A. Dunne Archive, boasts an extensive, unique collection of vintage photographs and maps of New York City. Customers can browse the collection online, though those keen on keepsakes need to stop by in person to pick up 8"x10" prints, such as an aerial view of the Empire State Building taken in 1964 ($50) or a glimpse of Central Park circa 1940 ($50). While the gallery also carries antique advertising art, handcrafted greeting cards, and full-scale models of the Brooklyn Bridge, today's Groupon can only be used toward the purchase of photographic prints and maps.
