The only Quagga that was ever photographed was a mare at the London Zoo in 1870. I don't know the subsequent history of that specimen and whether its skeleton or skin was preserved. The fact that this photo down below is, among others that were shot at the same time, the only photo that shows a living and healthy Quagga inspired me to use this for a life restoration.
I did it by painting it directly on the photograph using GIMP, to be as accurate as possible. I am really happy with the outcome, I think it might provide a lively picture of what this particular animal looked like in life.
Another good basis for a life restoration is the specimen down below:
It is the skin of the alleged last Quagga and is the least discoloured as far as I know.
Most Quagga reconstructions only show single individuals, so I plan to do a coloured drawing of a whole herd in their natural environment as well, showing them doing what they normally did.
