the Dholavira Signboard. The Harappans had arranged and set pieces of the mineral gypsum to form ten large symbols or letters on a big wooden board. At some point, the board fell flat on its face. The wood decayed, but the arrangement of the letters survived. The letters of the signboard are comparable to large bricks that were used in nearby walls. Each sign is about high and the board on which letters were inscribed was about long. The inscription is one of the longest in the Indus script, with one of the symbols appearing four times, and this and its large size and public nature make it a key piece of evidence cited by scholars arguing that the Indus script represents full literacy. A four sign inscription with large letters on sandstone is also found at this site, considered first of such inscription on sandstone at any of Harappan sites.
