Oh yeah, "Cool Ray Polaroid" shades. They came with a little tag that
had a small 1/2" dot of polarized material in the middle. You could
turn the tag 90 degrees to see the polarizing effect.

FWIW, that's still the best way to pick out polarized sunglasses from a
rack where they're mixed in with regular shades. Pick up an ugly pair,
turn them sideways, then select a better looking pair from the ones on
the rack that go opaque.
