Alec Guinness signed photo.  Obtained through purchase.  I bought off a dealer and cannot authenticate 100%.   Mr. Guinness was Obi Wan Kenobi in the Star Wars Holiday Special.  He was in a host of things related to Star Wars including the trilogy films, this and he voiced Ben again in a video game entitled:  "Star Wars".  He's been seen in footage in R2-D2 Beneath the Dome was well.
