The portrait is by Michael J. Deas who published published The Portraits and Daguerreotypes of Edgar Allan Poe, a comprehensive collection of images featuring authentic likenesses as well as derivative portraits of Poe. Michael was recently asked to authenticate a Poe daguerreotype by the Antiques Roadshow.
This is the 200th anniversary of Poe's birth, so it is fitting that he's immortalized on a stamp. I have to use them quickly before the price goes up again in May. As I was looking for illustrations of the new stamp, I found this charming necklace on Etsy.
