This is an image of George Curzon (1859-1925). He is seen in this photo in his robes as Viceroy of India, a post he held from 1899-1905. It is a logical step to assume this image is in the public domain. Its author is unknown (most likely an employee of the British Empire, and most likely long dead). I have uploaded it to the commons from the english language wikipedia. I will copy what was on its wikipedia page below :Half-length portrait of George Nathaniel Curzon, 1st Marquess Curzon of Kedleston, British statesman.Cropped and slightly touched up. Original from the Library of Congress.[1]LOC states: "No known restrictions on publication..no date recorded on caption card."Since Curzon died in 1925, the work is very likely in the public domain.
