I just put a photo over it, I probably could
paint that, I do paint large stage backdrops on occasion, it would be quite a project though. I think you can get that shrink wrap done now-a-days like you see all over advertising vehicles. I have no idea how much it would cost or how well it would work on an egg... I do like it though. I already thought of eventually turning our first trailer into an art trailer once we find a replacement.
