Up for auction is a very unique and rare pair of railroad glasses. From my quick research. I believe they are from the eighteen hundreds or perhaps early nineteen hundreds. I took photos with and without flash of the lenses. So you can get a good view of them. The first photo is most true to color these are a dark blue, very nice shade sunglass. The lenses look to be clean with some very slight scuffing. Please look at all photos. Thanks for your interest....p118
