Three studies of soldiers, some mounted, at a Royal occasion RMG PU9960, William Lionel Wyllie, before 1914 ?

Three studies of soldiers, some mounted, at a royal occasion the troops drawn up wear red tunics and white pith helmets, which suggests that despite the title this may be well before the first world war. Three hussars on white horses are shown top left and either two or three important uniformed men in horseback at bottom, one of whom appears to be a household cavalry officer. Date: before 1914 ?. Dimensions: 252 mm x 354 mm. Collection: Fine art.
