Each is a 13/16" litho and group includes the most famous planes and pilots well into the 1930s. This group displays VF with tiny traces of paint wear and the only exceptions being a slightly dented surface on #37 Eddie Rickenbacker and some near microscopic paint crazing on #s 54, 63 and 65. Among the more well-known button subjects are China Clipper, Wiley Post's plane, Captain Frank Hawks, Jimmie Mattern, Roscoe Turner, Howard Hughes and female pilots Loma Worth and Amy Johnson.
