The information that came with the sign says that it can be hung inside or outside, so right now it's on my front porch. I've only had this about a week, but so far it hasn't faded or discoloured at all. It's a good size and looks of good quality, the only thing I don't like is that it's made of plywood, I had expected it to be a solid board. Looking straight on though you can't tell the difference.
