Patricia from wonderful Agence eureka, a blog dedicated to vintage images, posted some vintage pictures of playmates on her archive blog, grenouille plus. Of course some of the pictures NSFW, but they are nice photos and some look almost naive. On the same post she suggested also a link to Rope Magic, a Japanese site (with some English menu) about bondage, just in case you have this fetish. BTW, some not safe pictures on this site too.
I love your comment that the pictures look naive. I commented there that it makes me a little sad to see these old style photos, which demonstrate clearer than words that times and the definition of beauty have changed.
yes, I think the women are pretties today, but the nudes are not made with a good taste most of the times.
Nice blog.I like this.
