Usually, only a single scribe signed a ceramic vessel, but multiple sculptors are known to have recorded their names on stone sculpture; eight sculptors signed one stela at Piedras Negras.
Biasanya hanya ada satu orang juru tulis yang menandantangani bejana keramik, tetapi beberapa pemahat dapat mencatatkan nama mereka di pahatan batu; sebagai contoh, delapan pemahat menandatangani satu prasasti di Piedras Negras.
