----------------------------Original message---------------------------- In our catalog, we have a listing for "International air routes of the world," World-Quincunial Projection, U.S. Coast & Geodetic Survey, 1946, 23 x 44 3/4 in., no scale given. It's in our off-site storage area, so I didn't actually look at the map, and we'd need some lead time to make it available for a reader. Also, not sure of its condition, so I can't comment on the possibilities of copying it. But contact us directly if you'd like to pursue this further at New York Public Library Map Division, (212) 930-0587, 5th Ave. & 42nd St., NYC 10018. Nancy Kandoian [log in to unmask]
