Mask Attachment(?)

Cleveland Museum of Art

Dark green stone or metal object with a triangular shape and rounded edges. The object is thicker on the left side and tapers to a point on the right side. Two holes are visible on the top side. The surface features a carved design with lines and geometric shapes. The design includes a bird-like figure on the left side. The background is a gradient from dark gray to light gray. The object appears to be an ancient artifact, specifically a mask attachment, by artist unknown.
