So I went to the Ghana Wikiproject today and noticed a message.1
tl;dr: The Wikimedia Netherlands has donated some 2,000 historic images, going back as far as almost a century related to Africa, South America and Southeast Asia.2
I am impressed and really thankful for such a generous donation to Wikimedia Commons relating to Ghana's history.
Now I guess it's about time we put those images to use!
I hope more are shared as and when they become available. Kudos, WMNL.
Checkout the category to find images about your country too. I've seen Guinea Bissau in there somewhere.
