This vibrant watercolour paintng shows the monarch with her feet up watching horse racing, while the Duke of Edinburgh fires a shotgun into the air, startling one of the Queen's corgis. The Princes Royal has attended the party with her horse, while her daughter, Zara, kisses her husband, Mike Tindall, who has shown up in his Rugby kit. This painting is a joyful celebration, and one in which you can always find another marvellous detail.
