Found a story online...One that interested my quite a bit.
If you have studied World War II at all, you should be familiar with the Auschwitz concentration camp. Over the entrance to the camp hung a huge iron sign that read 'Arbeit macht frei'(Work Sets You Free). The sign is huge, heavy and I would think hard as hell to transport without someone noticing.
The story spoke about how it might have been a high end collector or something that would have paid to have it taken. Seriously? What would you do with it? It's not like you're going to hang it in your living room and have friends over to view your new piece of 'art' and what good does it do ya to steal something of that size and end up stashing it in a dark corner somewhere?
I swear, people are weird man.
