“Aviatrix” is the feminine version of “aviator”, but of course you knew that already. This fabulous pair is courtesy Kemon’s Flickr stream, which has a huge array of mostly aviation-related stuff, a lot of it from the interwar pulp era!
Dorothy Sebastian (Wikipedia link) was apparently an early Hollywood actress.
Joan Blondell (Wikipedia again) was also a Hollywood actress, active from the 30s right through to post-WW2.
