Jayne Tracey coming down the staircase of Ewhurst Manor from Kamera No.51 (1963). I’m not sure if it’s the angle of the shot from below, but it looks like Jayne is either holding her chin up or maybe something caught her eye and is looking back up the stairs.
Lorraine Burnett descending some rather steep looking stairs nude as she gives her boobs a good squeeze accompanied by the familiar pout! Even so I’d still be at the bottom to catch her just in case!
Christine Jensen lounging across a staircase nude for Girl Illustrated Vol.3 No.26 (1969)
Margaret Nolan Posing Nude on a Staircase and With a Strategically Placed Banister Ball! Probably Taken on The Staircase of Ewhurst House, as There Are Other Shots of Other Models on the Same Staircase.
