I would be grateful if anyone could give me insight into this wool kilim (63x37 inches), including the meaning (if any) of the apparent writing “cm. 2. c.” in the upper portion of the rug. It was purchased in Istanbul in the early 1980s and was told at the time that it was a Tree of Life Thracian kilim that was at least 50 years old. It is in relatively good condition
