Shortbeard is a Munchkin Booty promotional card. It's a Door card.
The artwork on the card is a portrait of Robert Mitchell, who was the highest bidder at an auction for the right to get his image drawn by John Kovalic and put on a Munchkin card.
The card is a level 9 monster worth three treasures and one level. It has an extra +4 against British and French, and the bad stuff is that you lose all items with an 'A' in their name.
