As some of you are already aware, I'm going to bring out a 'Fillyfolio' soon featuring MLP:FiM's cutie mark crusaders in several adult situations. The final version is going to have 9 hi-res full color images with a number of bonus sketches of several other foals. There may be other special bonuses involved, but I'm still working on the specifics.
For now the base price is $5 for the entire set. I'll have more info closer to release.
