UNESCO's 'Heritage is identity, don’t steal it' Campaign

Unesco Published on 8 Oct 2014 

 Dear tourist, make sure that the souvenir you take home from Africa hasn’t been looted from a museum or illegally excavated from an archeological site. Please check its provenance and verify that it can be exported out of the country! Keep in mind that a cultural object is not simple merchandise: it embodies history and has a symbolic value for the local people. Help stop illicit trafficking!
