Goodyear-Zeppelin Company TransAtlantic Routes for Commercial Airships - circa 1929

Original company 10x8" b&w photo of proposed Atlantic routes. The norther route from NY to Paris nonstop is shown as 3100 nm, the central route has stops in Bermuda and the Azores (3800 nm) while the southern route also stops in Bermuda and then nonstop to Paris (4500 nm). Two-hole punched in left margin as with many other company-original photos. Very good.
