The image depicts a large circle with intricate swirling lines forming an abstract pattern. The designs resemble floral motifs or woven baskets, creating an ornate mandala. Stylized leaf-shaped motifs are in each corner, filled with intertwining linework. The design is bordered by a rectangular outline.
