Cover art : Photograph of Rosenda Monteros
[New York, Popular Library, 1962. SP 246. Movie tie-in : cheesecake photo on front cover; film poster on back cover].
The cover photo for Tiara Tahiti is of Mexican beauty Rosenda Monteros, who was popular in 1950s and 1960s. This was en era in which Hispanics, especially Mexicans, were often cast as Polynesians in South Seas movies, probably the best known example being Dolores Del Rio in Bird of Paradise (1932). Anyway, Rosenda certainly looks the part of a French/Tahitian maiden and the cover of the Popular Library reprint presents her in most beguiling fashion.
BTW the film now seems to be available in its entirety via YouTube
