First Day Covers of 1918 Air Post Stamps - Or Are They? by Ken Lawrence AFDCS Exclusive! The Jenny airmails may be among America’s best-known stamps, but little is known about the first day covers of those stamps. In fact, well-known philatelic author and researcher Ken Lawrence says there may only be one genuine FDC. First Day Covers of 1918 Air Post Stamps — Or Are They? brings together in one volume four previously published articles, along with a new “afterword” essay by Lawrence and an introduction by aerophilatelic exhibitor Andrew McFarlane. Publication coincides with the centenary of both U.S. airmail service and the issuance of the first U.S. airmail stamps, depicting the “Jenny” airplane. Unbound Printed Pages delivered by mail.
