This very rare 1985 Back to the Future 27x39 Single-Sided Movie Poster has been personally hand-signed in blue by Michael J. Fox (Marty McFly), Christopher Lloyd (Doc Brown), Thomas Wilson (Biff), Lea Thompson (Lorraine), Claudia Wells (Jennifer Parker), James Tolkan (Strickland), Donald Fullilove (Goldie Wilson) and Harry Waters Jr. (Marvin Berry) during their signings with Celebrity Authentics. In this 1980s sci-fi classic, small-town California teen Marty McFly (Michael J. Fox) is thrown back into the '50s when an experiment by his eccentric scientist friend Doc Brown (Christopher Lloyd) goes awry. Traveling through time in a modified DeLorean car, Marty encounters young versions of his parents (Crispin Glover, Lea Thompson), and must make sure that they fall in love or he'll cease to exist. Even more dauntingly, Marty has to return to his own time and save the life of Doc Brown. Ships affixed with a Celebrity Authentics serial-numbered and tamper evident Authentication Hologram and includes Celebrity Authentics Certificates of Authenticity featuring a picture of the actors signing poster.
