A wooden hunters' toolbox inscribed with an ancient writing system from Zambia has been making waves on social media.
"We've grown up being told that Africans didn't know how to read and write," says Samba Yonga, one of the founders of the virtual Women's History Museum of Zambia.
"But we had our own way of writing and transmitting knowledge that has been completely side-lined and overlooked," she tells the BBC.
It was one of the artefacts that launched an online campaign to highlight women's roles in pre-colonial communities - and revive cultural heritages almost erased by colonialism.
Another intriguing object is an intricately decorated leather cloak not seen in Zambia for more than 100 years.
