I have one of those... mine came with a pic of a man in a fedora or sorts on the backside. they are fragile. the plastic lens is really thin but removable. the plastic "frame" would not withstand too much knocking around and the area where the chain is wouldn't take a tug without cracking and snapping off being over 70 years old. I display mine with my Cruver recognition B-17 model. you can get similar modern ones from Etsy and eBay for cheap and if you loose it no big deal.
