Not sure of the two who had the biggest natural bush, either way it must have been an editing nightmare back then to hide it all for the censors!
Here we have Neva posing on the ‘Lantern Cottage’ set letting her hair down and showing it all and Sissi Mississippi at one with nature in the grounds of Ewhurst Manor.
Sissi on the other hand was always au natural and as a strip artist from Italy always refused to get rid of her magnificent bush (rightly so!). This was more common with continental models, where showing such plumage was more accepted.
Both images were published by Harrison Marks in Nature’s Intention Vol.1 No.1 ‘A Series of Natural Art Studies’ in 1969. For me I think Sissi edges it on sheer mass, but both look magnificent!
Thanks to Madmax for identifying the top model as Neva and not Velma Loftus!
