These? They are actually vinyl.
You will note that they have t-top mounting hardware rather than the velcro fits that you see on today's versions. They were produced by a company called Amtop in the early 1980s (patent below). The company is long gone. EBay and swap meets is the only source these days.

They fold and with storage bag, fit very nicely into the back of the car.
