Most microfiber cloths keep your screens or even your eyeglasses clean, but do nothing else. These Vintage PSA Art microfiber cloths from Declan do more. One side has the current NYC subway map (officially licensed with NYC MTA) and the second side features images and designs from the MTA archives (circa 1930-1960). Each package contains two cloths with the same dual-sided, sublimation-printed designs, one 12″ X 15.5″ and one 6″ X 8″. The Vintage PSA Art microfiber cloths are $21.99. Now you can always have a waterproof subway map with you as you navigate New York City.
