Alfred, Count d'Orsay, a true dandy even if he was not a genuine Count. Painted in 1839. More about him here:
A print of Teresa, Countess Guiccoli, a mistress of Byron, based on a drawing of her by d'Orsay.
A portrait of a boy by Hayter.
George Hayter (1792-1871) had a successful career as a portraitist, and Queen Victoria appointed him to be her 'Principal Painter in Ordinary' (a post previously held Joshua Reynolds and Thomas Lawrence), hence his knighthood; but he cannot be said to have been a portraitist of the highest quality. Even at the British court he became rather displaced by Winterhalter. But his early pictures of Victoria have real charm, and are in fact a familiar part of her iconography, even if most people, when shown one of them, could not identify the painter. This is Princess Victoria with her dog Dash,c.1836
Anna, Princess Hohenlohe-Langenburg; a study for a large painting of Queen Victoria's coronation, in which she is shown as one of the guests.
A detail from his painting of Queen Victoria's wedding. Though the arrival of Prince Albert, who had a relatively cultivated appreciation of art, was not beneficial to Hayter's prospects at court. The undoubted attractiveness of some his royal pictures is partly founded, I think, on a certain naivety of approach; so they do have a distinctive quality which is not to be found in the work of a more sophisticated society portraitist like Winterhalter.
