In her Plato Prehistorian: 10,000 to 5000 B.C. Myth, Religion, Archaeology, Mary Settegast reproduces a table which shows four runic character sets; a is Upper Paleolithic (found among the cave paintings), b is Indus Valley script, c is Greek (western branch), and d is the Scandinavian runic alphabet.
All those runes look like women with spread legs.
Thank you. From that runic alphabet you posted, I have been able to logically deduce what the object is.
It is a plaque with a runic number on it, bordered on top and bottom with decorative zig zag lines. Obviously, the plaque is shown sideways in the photo (to be fair, it has no clear top and bottom, so orienting it would be difficult). Plaques such as these were, no doubt, stuck into the mud wall near the doorways of their huts, so that they could tell them apart.
