Three generations of horsewomen posed for this photograph at Windsor, taken to mark The Queen’s seventy-eighth birthday: The Queen on Tinkerbell; her daughter, The Princess Royal, on Peter Pan; and her granddaughter Zara Phillips on Tiger Lily. All three skewbalds were bred by The Queen, who is well known for breeding a wide range of horses and ponies, from thoroughbred racehorses to Highland ponies. Tinkerbell is the mother of both Peter Pan and Tiger Lily.
