Three Vintage sleep masks, TWA and Air Canada memorabilia and one other sleep mask. The TWA mask was given out to first class passengers in the early to mid 1980s, has Beige/cream silk material on the outside, black cotton on the inside with an above nose padding and TWA Japan tag. It is used with some stretch on the elastic but no rips or tears.
Possibly the Air Canada one with the Air Canada Maple Leaf Logo is from the same time period or later, it hasn't been used. Also the pretty green one is new.
