Beautiful Rosenda Monteros was born on August 31, 1935 in Veracruz, Mexico. She’s best-known, here in the States for The Magnificent Seven (1960).
The photos shown here are publicity pictures for the 1962 comedy-drama Tiara Tahiti (1962, directed by Ted Kotcheff). The movie also stars James Mason and John Mills.
You can watch Tiara Tahiti on Prime Video. I haven’t been able to find it on dvd, unfortunately.
