The Indus Script—the remnants of the writing system of the Indus civilization—has been identified on seals and buildings and pottery, about 6,000 of them so far, used between about 2500 and 1900 BC. The glyphs are most often used on seals—rectangular ceramic objects that may (or may not) have been used to make marks in soft clay.
This image is from a recent report in Nature, discussing the latest side of the ongoing debate over whether the glyphs represent language or not. They made for a pretty photo essay, though.
