An educational poster with pictures and text which describes how scholars learn about the past through oral history, written sources and archaeology. It addresses questions including ' why do archaeologists dig?' , ' how do things come to be buried in the ground?' , and how do we know how old something is? It is one of five posters prepared for a Banda community event held in July, 2011. Printed versions of the posters are housed in the Banda Cultural Centre, Ahenkro.
