The field of stamp collecting is so broad that many collectors specialize. Notable specializations are aviation history and its sub-specialization, postal aviation history, which is collecting stamps, first-day covers, and cachets (designs printed on envelopes) marking historic events in the history of airmail.
This collection, compiled by Alfred Lippman, uses postal covers and cancellations to document the aviation history of Louisiana. It includes envelopes autographed by famous aviators, covers and cancellations marking important aviation events in Louisiana (such as the passing of the U.S.S. Akron, a naval zeppelin, over New Orleans) and, covers documenting important events in airmail history (such as the first flight of airmail from Atlanta to New Orleans).
This project was made possible in part by the generous support of the Gail and Alfred S. Lippman Family Fund.
