One of the most significant discoveries at Dholavira was made in one of the side rooms of the northern gateway of the city, and is generally known as 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 37 cm (15 in) high and the board on which letters were inscribed was about 3 m (9.8 ft) long. The inscription is one of the longest in the Indus script, with one symbol 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 big size letters on a sand stone is also found at this site, considered first of such inscription on sand stone at any of Harappan sites.
