I do not profess to be an artist, but I do think of porn as art, and myself an afficianado of porn--so that gives me maybe a good artistic eye? A debatable statement perhaps.
Anyway, in the course of looking for double files among my collection, I routinely find pics that are so similar in style or staging that they seem meant to be together, although they may come from wildly different time periods or genres. I'm not skilled enough at photoshop to really blend these expertly, but here are a few groups I though looked good together.
Let me know if this kind of thing is interesting, because I could do it all day.
