I dont have pictures of this particular rug, I just came across it a few days ago in a local rug shop. It was a nice silk qom (hunting scene) , nice color combinations, nice details...and then...there was a numerical code woven with the signature...something like NB1234 (just an example) . Is this normal? I'm wondering why such a traditional rug would include such a thing.
