The retro/vintage category has become really popular over the last few years. Do you have a site with multiple categories? Then you really
really should add a new category for retro/vintage/classic porn. That is, if you don't have one yet!
Payserve has the following sites in these niches:
RetroRaw - 699 movie galleries
Rodox - 419 photo galleries / 14 movie galleries
Rodox Retro style - 198 photo galleries
Feel free to hit me up if you need any pointers or info!
Other sponsors with classic porn sites: feel free to post your sites in this thread too!
