I've heard horror stories, I would NEVER donate anything to a museum. If they don't have the space they just trade between museums or sell off. This was a soldier bring back, in a regimental museum.
They are hard to display, as I wouldn't openly have it on the wall. How you see it in my office is about as open as I would ever display one. Just not for me to have large swastikas on open display, wife not ken either as she shares my office and has piano pupils in and out....
