In the realm of self portraits this series by Ed Wheeler might one of the most fun I've seen. Wheeler is a professional photographer and he began photographing himself as Santa in unlikely situations, like Santa gets a tattoo, a few years ago as a client Christmas mailer. The popularity of that drove him to continue the series while moving the focus to classic works of art. The finished products are fun and festive and they've even become their own set of Christmas cards at the Philadelphia Museum of Art. His blog is also full of fun Santa facts and details about his process.
