During the 11th Academy Awards, Walt Disney was presented with a unique Honorary Award for 'Snow White and the Seven Dwarfs.' Instead of a single gold statue, he received one full-sized Oscar and seven miniature ones, all mounted on a stepped wooden base. However, a more widespread 'wooden' era occurred during WWII (1943–1945). To support the war effort, the Academy gave out Oscars made of painted plaster rather than bronze and gold. Recipients were told they could trade them in for metal versions after the war ended. Additionally, the most famous 'mistake' in Oscar history occurred in 2017 when 'La La Land' was accidentally announced as Best Picture instead of 'Moonlight' due to a mix-up with the accounting firm's envelopes.
