Magnets feature the airships of the early 1900s.
One magnet pictures the U.S. Navy airship Los Angeles (originally the ZR-3 Zeppelin) mooring to the U.S.S. Patoka dirigible tender in 1925.
Another magnet is a photo portrait of Alberto Santos-Dumont (1873-1932) from 1909. Santos-Dumont, a Brazilian, designed, constructed and flew the first practical dirigibles, demonstrating controlled flight.
His place in aviation history was assured after he rounded the Eiffel Tower and won the Deutsch de la Meurthe race in 1901.
The third magnet pictures a montage of U.S. and German dirigibles.
These photos come from the Smithsonian collection.
