Persian [?] Carpet

I found this large rug the other day at one of my favorite junk shops. This one is pretty large at 5 ft x 10 ft. I have a ridiculous number of these which i've been finding very inexpensively over the last few yrs. They are 4 and 5 deep in my house now which i know is ridiculous. This one is different from my other ones. I don't know much about them either. My family gets them from Peter Papp and they pay a lot for them. I get them for next to nothing, so can never pass them up.
