Martha, my dear. :-)
Martha Longley was a fairly ubiquitous presence in fashion editorials and beauty ads in the late seventies and the eighties (the picture above is from a 1987 Cover Girl ad). She didn't quite become a household name on the level of Carol Alt or Christie Brinkley, though. It may have been because her "all-American" look became less of an asset as time went on and as modeling clients sought women with more "exotic" looks.
Ironically, she got her start with the Karins agency in Paris.
Martha Longley also tried her hand at acting. She appeared in the 1985 TV movie "California Girls" about a New Jersey auto mechanic (played by Robby Benson) who goes to the Golden State and woos a bikini model there (played by our heroine) while trying to get away from his overbearing mother. But it couldn't have been as entertaining as the real-life story of Bruce Springsteen marrying Julianne Phillips that same year, to the chagrin of his overbearing fans back home in New Jersey.
