Stella Jones by Terry Sparks from 1971 enjoying the sun on her naked body as she sunbathes. A fabulous pose on that sun lounger showing off her slender, svelte like body.

I remember my parents having a set of those loungers in the 70s as well. I also remember them being a bugger to extend out and legs regularly collapsing and having us in fits of laughter as the person sitting on it ended up in a big heap. :)
