I dug into a box of family artifacts the other day. Things I haven't yet photographed or figured out what to do with.
These glasses were such a find. I don't remember examining them before. They were my paternal grandfather's safety glasses when he was a leather cutter at Endicott-Johnson in Binghamton, NY. I love the hinged screen at the sides.
My family enjoyed looking at the glasses. We're a group of science nerds - some of us with years of experience wearing safety goggles or glasses. So it was easy to find a willing model.
