BECAUSE THIS RUG IS MISSING THE LABELING I AM ONLY ASSUMING WHAT THE PATTERN IT IS.  IT IS UP TO YOU TO DECIDE FOR YOURSELF, BASED ON WHAT YOU CAN UNCOVER ABOUT THE LOOK AND IMAGES THAT I HAVE POSTED IN THIS LISTING.

In looking on the internet for a similar rug this is what I have discovered.  
I believe this to be Karastan Lanamar in Kashan Design All Wool Face Machine Made in U.S.A. Area Rug 

I am assuming this is the Karastan pattern, Pattern No. 5517, because I have a similar, smaller Karastan, from the same estate that has this same look and it is pattern 5517, based on its labeling.
Approx. size is 1 foot 8.5 inches X 3 foot 2 inches (see images)

This rug is likely 70 to 100 years old.

Please see other rugs from this same estate, similar vintage, in my other Karastan listings. This rug has the art deco deep purple coloring that I like so much.
