The resemblance to Lord Voldemort is ironic, because in Harry Potter's last year Lord Voldemort came back to power and controlled Hogwarts, too. So in this year a portrait of HIM would have been normal. Harry granger 19:28, May 20, 2011 (UTC)

But this picture is in 1993 (Prisoner of Azkaban). It may be like an Easter Egg or something. —The preceding unsigned comment was added by (talkcontribs).

Either Easter Egg or perhaps a painting of Salazar Slytherin, his ancestor?
