I found these for a buck-fifty in Philadelphia about 16 years ago, in a weird little antique/pawn shop that felt like a front for some Mob operation. They are probably quite old, and certainly hand-crafted of what feels like tin and tin mesh. The temples are bits of bent wire, with careful little loops turned in the wire at the tips. I wore them for Halloween a couple years ago as part of an Invisible Man costume. Busy thinking hard, pushing harder on LAvoice. No time to wax any further here.
