We still have a limited quantity left of the Dual Autographed Photos signed by Keir Dullea and Gary Lockwood!
Each photo comes with a Certificate of Authenticity verifying these are original signatures. MRG sent a representative to meet up with the two 2001: A Space Odyssey stars in San Diego to have them sign the photos and HAL 9000 plates (plates now sold out) in person. The COA also includes a picture of the actors actually signing the photos and HAL 9000 plates.
The photos and plates were signed with the best high-quality pens so they will not fade or get erased over time. The actors liked the pens so much they kept them and wouldn't give them back! We didn't mind.
