4 black and white espresso-style mugs from Braniff International airline. Two are ceramic and two are plastic.
One ceramic mug has a chip on the bottom side of the handle (not noticeable unless turned over). The other ceramic mug has what looks like a very small chip on the bottom rim, but it is glazed, so likely more of an imperfection in the original production. The two plastic mugs have surface scuffing from use and one has a tiny nick in the top rim. See photos for more details.
