Well, this is stolen goods, so what harm can it do to steal a stolen good? It's a victimless crime basically, right? You subtly help yourself to one of the baroque decorated wall panels and, while unsuspiciously whistling, casually stroll out of the castle. You end up searching for your tent quite a bit longer, but it seems less of a chore with this great wall panel in tow. It becomes the centerpiece of your place back home, an incredible conversation starter, and one of your most prized possessions. Whenever people end up asking you about where you found it, you just demurely say "Oh this old thing? Found it while camping, would you believe."
