Yes, I did buy it,just got it and found out it's a silk onsilk qum. I'll post some pictures tomorrow morning.
Sold the isfahan and a heriz I got at the same auction at Christie's auction in New York. Interesting and learning process. It cost a far amount including money to put it in the auction. Over half the rugs didn't sell and the sellers had to absorb around $600. I did sell both and after deducting all my expenses and purchase price I made $8,200 which will never happen again,but does pay for all the other rugs I have on my floor. Most of the money came from the isfahan which sold for $10,000 including buyer's premium/
