- "And next to that [Biff's 1955 Ford Super De Luxe Convertible] was a lifelike wax figure of Biff! It was a pretty good likeness too — the same burly body and sloping forehead. They had even gotten the smirk right."
- —From Back to the Future Part II by Craig Shaw Gardner (quote, page 112)
A waxwork figure, also known as a wax sculpture, was a lifelike model of a famous person sculpted in wax.
Biff Tannen, who had become "the luckiest man on Earth" — as well as one of the richest and most powerful men in America — in the ABC timeline 1985A, had no doubt considered himself famous enough to have a waxwork figure made, which was on display at the main entrance of the Biff Tannen Museum, standing next to his newly-restored Ford Super De Luxe Convertible from 1955.
The waxwork figure of Biff was dressed in a smart dark gray suit, with a light gray handkerchief in the jacket's breast pocket; and a light gray open-necked shirt. It wore a gold chain round its neck, and held a lucky horseshoe in its left hand, signifying Biff's status as "the luckiest man on Earth"; while its right hand rested on the offside front of the car.
