18" X 21" Antique Hand Knotted Tibetan Meditation / Prayer Carpet Rug

Beautiful blue with a mandala pattern in blue, green, red, tan, brown, cream and black. I cannot establish the history of this prayer / meditation rug beyond the last owner who lived in Dharamshala in the 1960s. Because of the faded colors and uneven knotting I believe I can safely claim it to be at least 60 years old. It's probably under 100 years judging by the lack of uneven wear.
