It's unusual for me to disagree with you but I am sure the photo is of London Zoo's quagga mare which died in 1872 (and is now on display in the Edinburgh Museum). It is generally stated that this is the only quagga ever to have been photographed alive.
(I didn't think there were any known photos of the last Amsterdam quagga?)
Hello Tim, I have always been led to be believe there was documentary evidence. Please allow me some time to check back. The reason I was led astray was that the framework and clobbered stone holding mirrors some of the Amsterdam zoos' architecture.
Another feature article confirms that no photographic material is known of the living animal. Only this picture of the mounted specimen in the Amsterdam Zoological Museum is testament to this female quagga.
Hello Tim, I am sorry the book is in the Dutch language as it is really a fascinating read. It chronicles the history of their discovery on the Cape Province coast when the Khoikhoi were still masters of their own realm. Our Jan van Riebeeck basically turned South Africa and Cape Town already into an extractive exploitative trading post with the indigenous black population its first victims.
