- " 'Start talkin', kid. What else do you know about that book?' / Marty stuck the matchbook in his pocket. Biff was playing right into his hands. Now if he could just get him to tell him a bit more. / 'First,' Marty demanded, 'you tell me how you got it. How, when, where—' / Biff stared at him for another minute. / 'All right,' he agreed at last. He stood up and turned to the oil painting behind him [on the wall behind the desk in his private office] — a full-size portrait of Biff, like he was royalty or something. / He swung the painting out on its hinges, revealing the wall safe behind. / 'November 12, 1955,' he called over his shoulder as he started on the first of the three combination locks. 'That was when.' "

- "Biff opened the safe. He pulled a box off the center shelf, then dug a key out of his pocket and unlocked the box. He grinned and pulled out the Sports Almanac for Marty to see."

A safe was a strong, lockable steel container used to store valuables, which was either freestanding — being bolted to the floor — or secured into a wall. It could be locked and unlocked as required either by means of a key, or a combination lock.
In 1985A, Biff kept the almanac inside a locked metal box in a wall safe behind the desk in his private office at Biff Tannen's Pleasure Paradise Casino & Hotel. The safe was hidden from view behind a large oil painting of Biff himself, and was opened by not one but three combination locks.
In 1981, Biff also had a safe at his mansion in the alternate timeline, which Terry, who was part of the Hill Valley Civic Committee, attempted to break into to look for documents that might link Tannen to illegal activity so the committee could expose him as a criminal. It was believed that Biff was having dinner with his adopted family elsewhere and would not be at home, but Biff had in fact remained behind and caught Terry before he could open the safe. Terry was subsequently beaten to death by the corrupt Hill Valley Police Department, which Biff controlled.
