Willi Koopman, originally from the Netherlands, ventured into the US entertainment scene in the late 1960s, aiming to expand her acting career internationally. She made notable appearances in several popular TV shows of the era, including "It Takes a Thief," "The Outsider," "I Dream of Jeannie," "Jericho," and "The Man from U.N.C.L.E." This late 1960s headshot period offers a glimpse of her during this phase of her career.

If you are interested in more transparencies from this period you can find more HERE.

I also have a group of MYSTERY STILLS, which I can't determine the subject of the images. Have a look; maybe you can help identify the subjects.
