GRAY's SPORTS ALMANAC 1950-2000

 

This is the book that caused so much trouble for Doc and Marty during their second big adventure through time.  Biff brought this back to 1955 and gave it to his old self, allowing him to alter the future.

 

 

This is actually a blank notebook that used to be sold at the Back to the Future ride at Universal Studios.  I don't know if they still sell this there or not.  But it still makes a neat prop.
