This 11×14 “Vacation” Official Pix Shielded photo was personally hand-signed by Chevy Chase, who added extremely rare “Clark” character name, and Christie Brinkley, who added extraordinarily rare “The Girl in the Ferrari” character name. Both signatures and character name inscriptions were obtained during private, sit-down signings with Official Pix. The Official Pix authenticity hologram (058730), which can be accessed through the Official Pix database, is located on the back of the photo. This dual signed photo will add unique 1980’s Griswold style cinema to your autograph collection. If you have any questions, please ask.
