Dear Rufus Jr.
My name is Ric Dolphin and I am the deputy-editor of a charitable publishing company in Edmonton, Alberta, called the Society to Explore and Record Christian History (SEARCH). We are publishing a 12-volume illustrated history of Christianity and would like to use your Winged Horsemen as an illustration for a chapter on the siege of Vienna. Could you provide us with a high-res digital version of the painting and tell us what the fee would be. We generally pay around US$100.
