I like the radation warning sticker...When I was touring the Paul E Garber facality we were not allowed to get to close to some of the planes in one of the buildings because their was a rack which had several shelves with old Aircraft insturments on it, they said their was a radalogical hazard and we could not get any closer!, then the tour guid said it was kinda silly he had spent 20 some years setting in fron of them and was still ticking:)
