I've seen some pretty strange things in the galleries. My Mom is a painter, but works with other mediums (charcoal, pencil, etc.) and so were both of her parents. I still have paintings they did and some of the sketches from my grandma. Never saw anything that I would define as "beyond the pale" in THEIR work. However - here about six month ago I took my kiddo to the galleries near here. There was a section of very graphic artwork by Richard Turansky which just seemed dark to me and I ended up not looking through all of his paintings because of their nature.. I do prefer more of the traditional feel in things I would hang in my home, but it doesn't have to be raindows and unicorns and cute little bunnies, LOL!
