Steve the Wargamer put up a picture of The Chariot Race by Alexander von Wagner (1838-1919) on his blog and lamented the fact that he couldn't find a bigger image on the web (I couldn't either).
I went to Manchester a couple of years ago on a boring management awayday, but managed to escape in the afternoon and visit the Art Gallery where I saw this painting. The picture is huge; about four and a half feet by ten feet and in real life is quite breathtaking.
Anyway, I bought a large postcard of it so have scanned it at a larger size.
