Catherine Roberts' versatility as a model is reflected in this photo from a late-seventies lipstick and nail polish ad.
The soft expression in her face and the gentle subtlety in her magnificent eyes convey a sense of sweet, romantic innocence. :-)
The brand is L'Oreal, by the way, and the photo is from one of the those "L'Oreal Colors Your World" ads for lipstick and nail polish in colors named to represent different nationalities. This is from an ad for the "England" collection. I thought that "international" gambit L'Oreal went for in the late seventies was silly, and I said I wouldn't show photos from that series, but Ms. Roberts looks so ethereal here, I'm making an exception in this case. :-)
