I was just browsing earlier and I found the website http://www.oldfetishmags.com/

It contains mostly pin up photos of "ordinary" girls in poses designed to amuse and excite. Mostly of these were published in magazines like "Spick" and Span" and although there were not too many wetlook photographs, there are a few. A couple are reproduced here. It seems that digital copies of complete magazines are available.
