Original style floor mats?

Hey guys, does anyone know if these floor mats are really the original type that came with Duster's back in the day? They're at the bottom of page 109 in the legendary catalog.

I've got a 71 Duster and I always enjoy getting original type pieces for my car so I wouldn't mind getting a set of these if they are the original floor mats since my own are getting pretty ratty.
