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.
