The image shows three pieces of ancient stone artifacts displayed on a white wall. The artifacts are rectangular in shape and appear to be made of a light-colored material. Each piece has a small indentation in the center, which is likely a pattern or design. The indentations are arranged in a grid-like pattern, with each piece slightly overlapping the one below it.

The first piece on the left is slightly larger than the other two, and it is slightly smaller than the one on the right. It has a smooth, polished surface and appears to be slightly rough and uneven. The second piece in the middle is smaller and has a more rounded shape, while the third piece is larger and more rounded. All three pieces are attached to the wall with small white pins. The numbers "17" and "18" are visible on the top right corner of each piece.
