In addition, a graffito on a Phoenician sherd dated to the early to mid 7th century BCE and found at the Phoenician settlement of Doña Blanca near Cadiz has been identified as Tartessian by the shape of the signs. It is only two signs long, reading "]tetu[" or perhaps "]tute[." It does not show the syllable-vowel redundancy more characteristic of the southwestern script, but it is possible that this developed as indigenous scribes adapted the script from archaic Phoenician and other such exceptions occur (Correa and Zamora 2008).
