June was primarily a magazine model and this is a subject outside my area of expertise. (Translation: I don’t know jack about her career, except for the few scraps below.)
A couple of notes:
1958 – According to Celebrity Sleuth, these were her very first posed nudes. That seems like reliable info, given that June sent him the pictures! She had become the lead dancer at the famous Windmill Theater by then, although she was only 18. June had already been performing for six years by then, and had first been on stage topless at age 15. Within a few months after that photoshoot, she would be in Playboy (September, 1958 issue).
1959 – These are allegedly her breasts from The Immortal Mr. Teas
1987 – She did a nude scene in a film called Talking Walls. She was 47. (Video)
1999 – At age 59 she posed for some nudes to show that she was well preserved.
2003 – She was not in The House of 1000 Corpses, but they used an old pic from her youth
Here are some people who know WAY more than I do:
Vintage Erotica Forums has a thread with 17 pages of nude pictures

Damn… she was fine.
She also starred in the nudie cutie The Bellboy and the Playgirls directed by Francis Ford Coppolla. Unfortunately she kept her clothes on there. Coppolla also directed another nudity cutie Tonight For Sure with Marli Renfro who is Janet Leigh’s body double in Psycho.

I’m very sad to hear this. I interviewed her over the phone about the 45 of “Bikini With No Top On The Top” that she cut with Mamie Van Doren for our book, “Hollywood Hi-Fi.” She was very nice, talked to me for a long time, and had a great sense of humor in telling me stories about her life and career. She may have been nicknamed “The Body,” but there was a lot more to her than that.
She seems to have had a handle on things since her first appearances and represented the transition between the last true “pin-up era” and the start of the mainstream nude magazines. As far back as I can recall any sexual awareness, she was a part of that psyche. RIP and cheers to a life well lived.
She represented an era where nudity was accepted and she had an gorgeous body to boot! She was also talented but it’s too bad she got lousy films to exploit her physique rather than her acting talents.
