These are simply cool Vintage BCG military issued glasses. Total Military Birth Control Glasses. USS 4 1/2-5 3/4 are what the frames read. These are black in color and are in great shape for being vintage. Has of course light scratches, as well as on lenses, although if buying for the frames alone just pop out the lenses and have yours popped right back in, or do the fun thing and pop in clear non-script lenses to wear for the fashion!! Also selling tortoise color BCG's in separate auction. Found a few of these in black and brown and decided to keep a few for myself, and I'm sharing a few with you. Looks like Granddad had several!!! Very Retro and 50's looking, and perfect for any guy or girl looking for the "real" thing instead of store bought reproductions!! Perfect for the Pin Up or Mad Men Fan...
